案例二【背景资料】

某铁路标段有一座双线桥，主跨为(56+100+56)m连续梁；主墩位于水深5m的河流中，基础为桩基，低桩承台。桥位平面如图2所示。

基础施工期较长，施工计划跨汛期作业。混凝土由相邻标段负责提供。

施工单位进场后，项目经理部做了以下工作：

工作1：组织技术人员编制了该桥主跨的施工流程，如图3所示。

工作2：组织安全工程师和相关人员进行了危险源辨识，摘录会议部分记录如下：

(1)若栈桥贝雷梁材料多次重复使用，发生锈损，导致承载能力降低，可能会发生①。

(2)若塔吊超重作业，可能会发生②。

(3)0#段立模施工中，平台上若没有设置防护围栏，可能会发生③。

(4)若挂篮前移后安装锁定不牢，可能会发生向前④。

【背景资料】

某公司中标新建一座城市桥梁，该桥由主桥、南引桥、北引桥组成。该桥桥跨布置为（40m×3）×5+（118m+246m+118m）+（40m×3）×5，采用东、西两幅分离式结构，单幅桥宽W为11.5m，两幅桥间的中央分隔带宽1.5m。

主桥上部结构为钢箱梁斜拉桥；引桥上部结构为40m 装配式后张法预应力混凝土 T梁，每跨的相邻两片T梁之间用5片中横隔板和2片端横隔板连接，引桥单幅横断面图如图3所示。该引桥上部结构拟采用双导梁架桥机或跨墩龙门吊进行T梁架设。

图3 引桥单幅横断面图

该桥梁主桥所跨水域运输条件良好，河道上下游能通行的最近桥梁在10km之外，引桥均处于农田富水地带，征地困难。

该桥下部结构采用肋板式桥台，桩柱式桥墩，钻孔灌注桩基础。其中引桥和主桥过渡墩为摩擦桩，桩径1.5m，桩长在 41m至45m 之间；主桥主墩为端承桩群桩，桩径为 1.8m，桩长在55m至58m之间，设计要求每根端承桩嵌入硬质岩层深度为8m。施工现场有长螺旋钻、旋挖钻、冲击钻、静力压桩机等桩基施工设备可供选择。主墩所在水域年常水位高程66.0m，年最高水位高程67.5m，年最低水位高程64.3m。主墩承台采用围堰施工，施工工序包括：①封底；②绑扎钢筋；③施作围堰；④浇筑混凝土；⑤抽水；⑥凿除桩头。

The time for sharpening pencils, arranging your desk, and doing almost anything else instead of writing has ended. The first draft will appear on the page only if you stop avoiding the inevitable and sit, stand up, or lie down to write. (41)_________

Be flexible. Your outline should smoothly conduct you from one point to the next, but do not permit it to railroad you. If a relevant and important idea occurs to you now, work it into the draft. (42)_________ Grammar, punctuation, and spelling can wait until you revise. Concentrate on what you are saying. Good writing most often occurs when you are in hot pursuit of an idea rather than in a nervous search for errors.

(43)_________ Your pages will be easier to keep track of that way, and, if you have to clip a paragraph to place it elsewhere, you will not lose any writing on the other side.

If you are working on a word processor, you can take advantage of its capacity to make additions and deletions as well as move entire paragraphs by making just a few simple keyboard commands. Some software programs can also check spelling and certain grammatical elements in your writing. (44)_________ These printouts are also easier to read than the screen when you work on revisions.

Once you have a first draft on paper, you can delete material that is unrelated to your thesis and add material necessary to illustrate your points and make your paper convincing. The student who wrote “The A & P as a State of Mind” wisely dropped a paragraph that questioned whether Sammy displays chauvinistic attitudes toward women. (45)_________

Remember that your initial draft is only that. You should go through the paper many times – and then again – working to substantiate and clarify your ideas. You may even end up with several entire versions of the paper. Rewrite. The sentences within each paragraph should be related to a single topic. Transitions should connect one paragraph to the next so that there are no abrupt or confusing shifts. Awkward or wordy phrasing or unclear sentences and paragraphs should be mercilessly poked and prodded into shape.

[A] To make revising easier, leave wide margins and extra space between lines so that you can easily add words, sentences, and corrections. Write on only one side of the paper.

[B] After you have clearly and adequately developed the body of your paper, pay particular attention to the introductory and concluding paragraphs. It’s probably best to write the introduction last, after you know precisely what you are introducing. Concluding paragraphs demand equal attention because they leave the reader with a final impression.

[C] It’s worth remembering, however, that though a clean copy fresh off a printer may look terrific, it will read only as well as the thinking and writing that have gone into it. Many writers prudently store their data on disks and print their pages each time they finish a draft to avoid losing any material because of power failures or other problems.

[D] It makes no difference how you write, just so you do. Now that you have developed a topic into a tentative thesis, you can assemble your notes and begin to flesh out whatever outline you have made.

[E] Although this is an interesting issue, it has nothing to do with the thesis, which explains how the setting influences Sammy’s decision to quit his job. Instead of including that paragraph, she added one that described Lengel’s crabbed response to the girls so that she could lead up to the A & P “policy” he enforces.

[F] In the final paragraph about the significance of the setting in “A & P,” the student brings together the reasons Sammy quit his job by referring to his refusal to accept Lengel’s store policies.

[G] By using the first draft as a means of thinking about what you want to say, you will very likely discover more than your notes originally suggested. Plenty of good writers don’t use outlines at all but discover ordering principles as they write. Do not attempt to compose a perfectly correct draft the first time around.

【背景资料】
某集团公司承建普速铁路综合第一标段。主要项目内容有:路基、桥涵、隧道、电力、电力牵引供电、通信及信号工程。
部分工程情况如下:隧道3座，均为双线隧道其中2号隧道起止里程为长度1900m。进、出口各DK30+600～~DK32+500，设明洞1处，均为偏压明洞。最大埋深约130m，洞身围岩为Ⅲ、IV、V级石英砂岩、砂岩、绢云母片岩，局部夹少量页岩，岩体较破碎。
事件一:为满足施工需求，拟现场建设混凝土拌和站。项目经理部工程部编制了拌和站现场平面布置和场区内牌图设置规划方案。
方案内容为:拌和站内规划布置混凝土搅拌机组区、保障系统区、办公区和生活区;场区内设置施工现场平面图、工程概况牌、管理人员名单、消防保卫牌及监督电话牌。
该方案经项目技术负责人审核，认为规划方案内容不全，要求修改完善。
事件二:混凝土拌和站站内配置一套HZS120型混凝土搅拌设备，该设备实际生产能力为2m3/盘。隧道二次衬砌C30混凝土理论配合比如表4-1所示，每立方米混凝土水泥(P.O42.5）用量为325kg。某日拟进行隧道二衬混凝土灌注作业，在拌和站搅拌混凝土前，拌和站试验人员对粗、细骨料的含水率进行了测定，测得细骨料砂子含水率为6.5%，粗骨料碎石含;水率为0.4%，据此确定了施工配合比。

事件三:项目经理部工程部编制了2#隧道施工作业指导书，相关内容有:
（1）隧道爆破采用光面爆破，减少对围岩的扰动，控制围岩变形。
（2）隧道初期支护采用喷锚支护，喷射混凝土采用干喷工艺。
（3）隧道深埋地段二次衬砌应在初期支护完成后立即施作。
（4）隧道仰拱填充与仰拱混凝土同时同强度等级灌注。
（5）隧底超挖部分应采用C25片石混凝土回填。
事件四:根据铁路建设项目施工企业信用评价办法，信用评价得分是从基础分中减去项目日常检查扣分和不良行为扣分，加上标准化绩效管理考评得分。在开工第一年第三季度建设单位组织的信用评价考核过程中，标段信用评价扣分情况如表4-2所示。

事件五:接触网弹性吊索安装前，项目经理部对施工队进行了技术交底，要求弹性吊索安装应按自下锚侧向中心锚结的顺序进行安装，一个锚段吊索紧固张力时，弹性只能有两个作业面;弹性吊索张力紧线器应位于中心锚结侧，以改善接触网悬挂点的弹性，降低受电弓的离线率，提高取流质量。
事件六:项目经理部编制了信号工程施工方案，具体施工工序为：电缆线路复测→光电缆敷设→A→室外箱盒安装配线→B→室内设备安装配线→室内外设备自检、单体调试→C→室内外联锁试验→竣工验收。

关于行政确认的制度功能，以下说法正确的有（     ）。

【背景资料】建设单位发包一年产量60万吨的煤矿工业广场项目。经过招标投标，某施工单位中标并与建设单位签订了施工合同，工程内容包括提升机房、变电所、机修车间、办公楼等，合同总价2800万元。施工期间，发生以下事件：
事件1：开工前，施工单位根据合同工期编制了施工进度计划网络图（如下图1），并报监理工程师审核。监理工程师发现，按照设计文件，工作H和工作I完成后，工作J方可施工，这在进度计划网络图中没有体现，不符合“四结合”的施工准备方法，要求施工单位进行调整。

事件2：工程开工后不久，施工单位项目经理王某因个人原因与单位解除劳动合同，施工单位决定由项目副经理李某担任项目经理。
事件3：办公楼工程F的钢筋混凝土预制桩基础施工期间，由于建设单位供应的预制桩到场不及时，使桩基础推迟5天开工。打桩过程中，施工单位的打桩设备出现故障造成工程停工3天。设备修理完毕恢复施工后，突发洪水，导致工程停工7天。
