摘要武汉市每年的降水量很大，长时间的降水对工程建设造成严重影响，本文论述在武汉大雨及以上的强降水或是导致的恶劣的自然灾害时，从工程的材料，建设，运输，资金等方面入手，通过对文献研究，定性的分析影响建设工程的成本因素。接着归纳出近几年武汉由强降雨引发的自然灾害致使建设工程产生的问题，总结出各种建设成本分析，以及如何安全的施工合理的控制成本，着重写了建设工程对洪水的应对。最后通过武汉地铁坍塌案例，分析事故原因，提出进一步巩固。关键词：强降雨，洪水，坍塌，建设工程，成本AbstractTheannualprecipitationinWuhanislarge,longtimeprecipitationcausedseriousimpactontheengineeringconstruction,severenaturaldisastersintheWuhanheavyrainandstrongprecipitationoverorasaresultoftheproject,fromthematerial,construction,transportation,financeandotheraspects,throughtheresearchonthepresentcostfactors,qualitativeanalysiseffectoftheconstructionproject.ThensummedupinWuhaninrecentyearsbytheheavyrainfallcausedbynaturaldisastersresultinginconstructionengineeringproblems,summeduptheanalysisofthecostofconstruction,andtheconstructioncostcontrolhowsafeandreasonable,itfocusesontheconstructionprojectofthefloodresponse.Finally,throughthecaseofWuhansubwaycollapse,analysisofthecausesoftheaccident,tofurtherconsolidate.Keywords:heavyrainfall,flood,collapse,constructionproject,cost目录摘要..................................................................................................IAbstract.........................................................................................II目录.......................................................................................III1.引言.........................................................................................11.1研究背景...........................................11.2强降水的等级划分...................................12.强降雨对各种成本的影响...................................................22.1材料成本...........................................22.1.1砌块...............................................22.1.2钢材...............................................22.1.3构件..............................................32.2建设成本...........................................32.2.1土方和基础工程....................................32.2.2混凝土，砌体，抹灰工程............................42.3运输成本...........................................42.3.1运输量.............................................42.3.2运输方式...........................................52.4资金成本...........................................52.5设计变更成本.......................................52.6排水清淤成本.......................................53武汉现几年由强降雨引发的工程问题.................................53.1工程积水，倒灌......................................63.2洪水内涝............................................73.3施工坍塌............................................83.4施工运输受影响......................................93.5工程终止............................................94武汉市由强降雨引发问题的成本控制分析.......................104.1建设材料的防水等各项性能及维护成本分析及报表.......104.2工程建设成本分析及报表.............................114.3建设运输成本分析及报表.............................124.4建设资金成本分析...................................124.5建设变更成本分析及报表.............................135强降雨下的减损建议...............................................................
