【背景资料】
某城市道路改造工程,道路施工的综合管线有0.4MPa的DN500中压燃气、DN1000给水管网并排铺设在道路下,燃气管道与给水管材均为钢管,实施双管合槽施工。热力隧道工程采用暗挖工艺施工。承包方A公司将工程的其中一段热力隧道工程分包给B公司,并签了分包合同。
(1)B公司发现土层松散,有不稳定迹象,但认为根据已有经验和这个土层的段落较短,出于省事省钱的动机,不仅没有进行超前注浆加固措施,反而加大了开挖的循环进尺,试图“速战速决,冲过去”,丝毫没有理睬承包方A公司派驻B方现场监督检查人员的劝阻。结果发生隧道塌方事故,造成了3人死亡。
(2)事故调查组在核查B公司施工资格和安全生产保证体系时发现,B公司根本不具备安全施工条件。

【背景资料】
某施工单位承建一跨堤桥梁工程,该桥为三跨预应力混凝土连续梁桥,跨径布置为48m+80m+48m,上部结构为预应力混凝土箱梁,箱梁顶宽14.5m,底宽7.0m,箱梁高度由6.0m渐变到2.5m。施工单位组建了项目经理部,施工过程中发生了如下事件:
事件一:项目经理部在详细踏勘现场后,编制了实施性施工组织设计,并要求由上部结构劳务分包单位编制挂篮专项施工方案,项目经理部再按规定进行报批。
事件二:项目经理部经过分析比选,决定上部结构悬臂浇筑挂篮采用菱形挂篮,挂篮如图3所示,强调挂篮与悬浇筑梁段混凝土的重量比不宜大于A,且挂篮的总重应控制在设计规定的限重之内,并为挂篮中构件B、C、D的质量作了特别要求。
事件三:项目总工程师在挂篮施工前进行了详细的安全技术交底,强调严格按规范要求实施,混凝土的强度不低于设计强度等级值的E,弹性模量应不低于混凝土28d弹性模量的F,当采用混凝土龄期代替弹性模量控制时应不少于G天,两端张拉时,各干斤顶之间同步张拉力的允许误差宜为H。
事件四:挂篮施工进行到5号梁段,浇筑完混凝土拆除内模板时发现腹板部分位置存在厚度不均缺陷,项目经理部经过认真分析,找出了造成缺陷的可能原因,包括模板设计不合理、箱梁模板产生位移(模板没有固定牢固,使内、外模板相对水平位置发生偏差)等模板本身及施工方面的原因。

不考虑其他影响因素,请根据上述背景信息回答以下题目。
A市B县C镇有丰富的石膏资源,该地有甲、乙两座石膏矿,两矿开采的为同一矿体。乙石膏矿位于甲石膏矿浅部的西南,开采深度为+115~-110m ,甲石膏矿开采深度为+120~-32m 。 乙石膏矿北部边界和甲石膏矿的西北部南边界平行对应,东部边界和甲石膏矿南部的西边界平行对应。 两矿上覆石灰岩层相同且完整,无断层切割,只是厚度不同。乙石膏矿的上覆灰岩的厚度为30~ 120m ,甲石膏矿为85~200m。
两矿开采工艺相同,设计矿柱有所不同。两矿均采用浅孔房柱法开采,设计矿房宽度均为8m ,乙石膏矿设计采用连续矿柱和间断矿柱,连续矿柱宽 6m,间断矿柱6mX6m, 连续矿柱和间断矿柱间隔布置;甲石膏矿设计全部采用连续矿柱,宽6m。
2014 年乙石膏矿由于采矿许可证到期加之经营不善,于2014年3月15 日停产,之后开始与甲石膏矿商洽整合事宜。2014年6月18日,甲石膏矿与乙石膏矿签订整合协议,一次性支付给乙石膏矿600万元,乙石膏矿将全部资产整体移交甲石膏矿,但由于手续问题两矿的整合一直被搁置, 乙石膏矿一直处于无人管理状态。
2015年 12月 25日0时 17 分,甲、乙两矿所在区域内发生3.2级地震,之后7 次0.9~2.9 级地震,之后地面塌陷变形,感觉塌陷时地面像跳舞状起伏波动,方向由乙石膏矿自西向东 塌陷涉及乙石膏矿、甲石膏矿,并出现陷落坑。 坍塌造成甲石膏矿当班 29 名井下作业人员被困。
经过科学组织,全力搜救,至2015年 12 月26日0时 15 分,成功救出王某等 11 名被困矿工,这 11 名矿工均有不同程度的受伤 。该起事故最终造成1 人死亡, 13 人失踪。
经调查造成事故的直接原因是乙石膏矿采空区经多年风化、蠕变,采场顶板垮塌不断扩展,使上覆巨厚石灰岩悬露面积不断增大,超过极限跨度后有关巷道发生冲击地压事故,灰岩层积聚的弹性能瞬间释放形成矿震,引发相邻甲石膏矿上覆石灰岩垮塌,井巷工程区域性破坏。
根据以上场景,回答下列问题:
某机电安装公司承担北方某城市锅炉房安装工程,主体设备为3台蒸发量25t/h、 蒸汽压力为2.5MPa的散装工业锅炉。
开工前,项目部根据锅炉房安装工程施工组织设计,进行全面的质量策划,并指 令专业工程师编制质量控制程序。施工过程检查中,发现某焊工的合格证已过有效期。 分项工程质量验收时,发现存在以下质量问题:
问题一:锅炉本体已安装完毕,但锅炉钢架中1根立柱局部垂直度超差。
问题二:锅炉主蒸汽管道上,有一段管道壁厚比设计要求小1mm,除壁厚外,其 他均满足设计要求。
工程在供暖期到来时完工,但因建设单位配套设施不完善,没能进行系统试运行。 当寒潮突然袭击,气温骤降后,发现一台主要设备和部分阀门冻裂,经查是因为施工单 位在水压试验后,残留的水没有排净造成的,施工单位对此事故进行了处理。
[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.
