【背景资料】

某公路隧道设计为双向四车道分离式隧道，沥青混凝土路面，隧道合同总工期为36个月。开工日期为2018年7月---2021年7月竣工.

左右隧道分别长4855m，中线间距30m，隧道最大埋深850m，纵坡为3%人字坡，其地质条件为：岩性为砂岩、石灰岩，局部有煤系地层；瓦斯含量低，属低瓦斯隧道；穿越F1、F2、F3三条断层；地下水发育。左、右洞围岩级别均为：Ⅱ级3415m，Ⅲ级540m，V级310m，V级590m。在距进口2100m（对应里程K27+850）处设计了一座斜井，斜井长450m，向下纵坡5%~8%，隧道纵断面示意图及平面布置示意图分别见图5-1、图5-2。

施工中发生如下事件：

事件一：施工单位进场后，经现场调查发现，进口处为深沟，且跨沟桥台位于隧道洞口。经综合考虑，施工单位提出了设计变更方案，在距进口280m处增设一条长150m的横洞（见图5-2）。

事件二：施工单位根据《公路桥梁和隧道工程施工安全风险评估指南(试行)》,在总体风险评估基础上,对右线隧道开展了总体风险评估,确定风险等级为IV级。

2019年7月6日上午,隧道开挖时,量测人员在处理量测数据中,发现“周边位移时间曲线”出现反弯点,但未及时告知作业班组潜在的危险,当日下午发生较大塌方,当场死亡5人,重伤12人。

【背景资料】某施工单位承建了一段二级公路沥青混凝土路面工程，路基宽度12m。上面层采用沥青混凝土(AC-13)，下面层采用沥青混凝土(AC-20);基层采用18cm厚水泥稳定碎石，基层宽度9.5m;底基层采用级配碎石，沥青混合料指定由某拌和站定点供应，现场配备了摊铺机、运输车辆。基层采用两侧装模，摊铺机铺筑。
施工过程中发生如下事件：
事件一：沥青混凝土下面层施工前，施工单位编制了现场作业指导书，其中部分要求如下:(1)下面层摊铺采用平衡梁法;(2)摊铺机每次开铺前，将熨平板加热至80℃;(3)采用雾状喷水法，以保证沥青混合料碾压过程不粘轮;(4)摊铺机无法作业的地方，可采取人工摊铺施工。
事件二：施工单位确定的级配碎石底基层实测项目有：压实度、纵断高程、宽度、横坡等。
事件三：施工单位试验室确定的基层水泥稳定碎石混合料的集料比例如表1所示，水泥剂量为4.5%(外掺)，最大干容重为2.4t/m³，压实度98%。

It was only after I started to write a weekly column about the medical journals, and began to read scientific papers from beginning to end, that I realized just how bad much of the medical literature frequently was. I came to recognize various signs of a bad paper: the kind of paper that purports to show that people who eat more than one kilo of broccoli a week were 1.17 times more likely than those who eat less to suffer late in life from pernicious anaemia. (46) There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generates both health scares and short-lived dietary enthusiasms.

Why is so much bad science published? A recent paper, titled ‘The Natural Selection of Bad Science’, published on the Royal Society’s open science website, attempts to answer this intriguing and important question. It says that the problem is not merely that people do bad science, but that our current system of career advancement positively encourages it. What is important is not truth, but publication, which has become almost an end in itself. There has been a kind of inflationary process at work: (47) nowadays anyone applying for a research post has to have published twice the number of papers that would have been required for the same post only 10 years ago. Never mind the quality, then, count the number.

(48) Attempts have been made to curb this tendency, for example, by trying to incorporate some measure of quality as well as quantity into the assessment of an applicant’s papers. This is the famed citation index, that is to say the number of times a paper has been quoted elsewhere in the scientific literature, the assumption being that an important paper will be cited more often than one of small account. (49) This would be reasonable enough if it were not for the fact that scientists can easily arrange to cite themselves in their future publications, or get associates to do so for them in return for similar favors.

Boiling down an individual’s output to simple metrics, such as number of publications or journal impacts, entails considerable savings in time, energy and ambiguity. Unfortunately, the long-term costs of using simple quantitative metrics to assess researcher merit are likely to be quite great. (50) If we are serious about ensuring that our science is both meaningful and reproducible, we must ensure that our institutions encourage that kind of science.

背景材料：

某公司承建一座桥梁工程，采用左右双幅分离式结构，上部结构采用跨径组合为（30m×5）×3联先简支后连续箱梁，每幅每跨4片中梁，2片边梁。下部结构墩柱基础采用钻孔灌注桩，强度等级C25，桥台采用桩接盖梁的轻型桥台，如图2-1所示。

施工前项目部编制相关施工方案：

（1）上部结构装配式梁板施工，在一片空旷地区设置梁场进行梁板预制，四周设置围挡封闭管理，大门口设置五牌一图，包括工程概况牌、管理人员名单及监督电话牌等。采用跨墩龙门吊进行梁板架设，架梁之前完成龙门吊的组装及检查。

（2）梁板架设完成之后，进行横隔板、湿接头和湿接缝的钢筋模板安装及混凝土浇筑，桥梁1号墩处横断面Ⅰ-Ⅰ如图2-2所示。钢筋进场后进行见证取样，检测钢筋的力学性能，合格后进场使用。桥梁湿接头混凝土浇筑前先穿束，浇筑完成后进行负弯矩预应力筋的张拉以及孔道压浆，压浆过程中发现有些孔道堵塞。

（3）下部结构墩柱施工时，为了提高墩柱整体稳定性，在柱与柱之间设置结构B；施工完成后进行墩柱垂直度检测，偏差为10mm，符合设计及相关规范要求。

[A] The first and more important is the consumer’s growing preference for eating out; the consumption of food and drink in places other than homes has risen from about 32 percent of total consumption in 1995 to 35 percent in 2000 and is expected to approach 38 percent by 20This development is boosting wholesale demand from the food service segment by 4 to 5 percent a year across Europe, compared with growth in retail demand of 1 to 2 percent. Meanwhile, as the recession is looming large, people are getting anxious. They tend to keep a tighter hold on their purse and consider eating at home a realistic alternative.

[B] Retail sales of food and drink in Europe’s largest markets are at a standstill, leaving European grocery retailers hungry for opportunities to grow. Most leading retailers have already tried e-commerce, with limited success, and expansion abroad. But almost all have ignored the big, profitable opportunity in their own backyard: the wholesale food and drink trade, which appears to be just the kind of market retailers need.

[C] Will such variations bring about a change in the overall structure of the food and drink market? Definitely not. The functioning of the market is based on flexible trends dominated by potential buyers. In other words, it is up to the buyer, rather than the seller, to decide what to buy .At any rate, this change will ultimately be acclaimed by an ever-growing number of both domestic and international consumers, regardless of how long the current consumer pattern will take hold.

[D] All in all, this clearly seems to be a market in which big retailers could profitably apply their scale, existing infrastructure and proven skills in the management of product ranges, logistics, and marketing intelligence. Retailers that master the intricacies of wholesaling in Europe may well expect to rake in substantial profits thereby. At least, that is how it looks as a whole. Closer inspection reveals important differences among the biggest national markets, especially in their customer segments and wholesale structures, as well as the competitive dynamics of individual food and drink categories. Big retailers must understand these differences before they can identify the segments of European wholesaling in which their particular abilities might unseat smaller but entrenched competitors. New skills and unfamiliar business models are needed too.

[E] Despite variations in detail, wholesale markets in the countries that have been closely examined-France, Germany, Italy, and Spain-are made out of the same building blocks. Demand comes mainly from two sources: independent mom-and-pop grocery stores which, unlike large retail chains, are too small to buy straight from producers, and food service operators that cater to consumers when they don’t eat at home. Such food service operators range from snack machines to large institutional catering ventures, but most of these businesses are known in the trade as “horeca”: hotels, restaurants, and cafes. Overall, Europe’s wholesale market for food and drink is growing at the same sluggish pace as the retail market, but the figures, when added together, mask two opposing trends.

[F] For example, wholesale food and drink sales come to $268 billion in France, Germany, Italy, Spain, and the United Kingdom in 2000-more than 40 percent of retail sales. Moreover, average overall margins are higher in wholesale than in retail; wholesale demand from the food service sector is growing quickly as more Europeans eat out more often; and changes in the competitive dynamics of this fragmented industry are at last making it feasible for wholesalers to consolidate.

[G] However, none of these requirements should deter large retailers (and even some large good producers and existing wholesalers) from trying their hand, for those that master the intricacies of wholesaling in Europe stand to reap considerable gains.
