摘要地质是人类进行工程建设的载体，不同的地质环境对工程建设的承受能力不同，因此会制约该区域的工程建设。尽管我国的工程建设事业飞速发展，但地质条件对工程建设的影响依旧不容忽视。喀斯特地区地质条件复杂，自然灾害频发，在此进行工程建设难度大、成本高，能否正确认识工程地质条件，处理地质问题，关系到工程项目能否顺利建设、安全运营及其造价高低。对喀斯特地质认识不足或处理不当，不仅会带来工程事故，大大增加工程造价，还会带来各种工程遗留问题，增加后期运营和维护费用，造成总成本的增加。因此，重视地质问题，保证勘察资料准确性，优化设计，合理施工以及后期维护是降低喀斯特地质区工程总造价的重要途径。关键词：喀斯特地质；勘察；设计；工程造价ABSTRACTGeologyisthecarrieroftheconstructionofhumanengineering,thedifferentgeologicalenvironmentontheconstructionofthebearingcapacityisdifferent,soitwillrestricttheconstructionoftheregion.DespitetherapiddevelopmentofChina'sengineeringconstruction,buttheimpactofgeologicalconditionsontheconstructionoftheprojectcannotbeignored.ThegeologicalconditioniscomplicatedinKarst,frequentnaturaldisasters,theconstructiondifficultyandhighcost,thecorrectunderstandingofengineeringgeologicalconditionsandgeologicalproblemsrelatedtotheprojectconstruction,safeoperation,lowcost,lackofknowledgeonKarstgeologyorimpropertreatmentwillnotonlyresultinengineeringaccident,greatlyincreasetheprojectcostwillbringavarietyofengineeringproblems,increasethelateoperationandmaintenancecosts,increasethetotalcost.Therefore,itisanimportantwaytoreducethetotalcostofKarstgeologicalareatopayattentiontogeologicalproblems,ensuretheaccuracyofsurveydata,optimizethedesign,reasonableconstructionandmaintenance.Keywords:Karstgeology;survey;design;engineeringcost目录1绪论..............................................................................................................................................11.1研究背景..................................................................................................................................11.1.1喀斯特地质..........................................................................................................................11.1.2喀斯特地质对工程的影响...................................................................................................11.1.3宜万铁路地质情况介绍.......................................................................................................11.2研究目的..................................................................................................................................11.3研究意义..................................................................................................................................21.3.1经济意义..............................................................................................................................21.3.2技术意义..............................................................................................................................21.3.3社会意义..............................................................................................................................22.1勘察设计阶段地质对造价的影响...........................................................................................22.1.1勘察不准确增加设计变更成本...........................................................................................22.1.2勘察失误造成施工事故增加造价..................
