摘要本设计是在对拟建建筑物场地进行的岩土工程勘察结果上进行的。通过土工试验、原位测试等测试手段得到该场地地基土的各种指标，利用这些指标根据规范要求计算了各层土的物理力学指标和各层土的承载力特征值，分析场地的主要工程地质问题，由于拟建建筑物的地基土承载力小于基底压力，不能满足设计要求，所以需要进行地基处理，依据场地地基土工程地质性质，结合上部结构特点对场地的工程地质条件、地基稳定性、地震效应、场地类别进行了分析判断，提取岩土工程勘察报告并对其地基处理方案进行分析论证，选出本场地地基处理的最佳方案为水下钻孔灌注桩。关键词工程地质条件岩土工程勘察工程地质问题地基处理技术AbstractThisdesignbelongstoaccordingtothehebeiuniversityofengineeringentrustsThecoalindustrydesignandresearchinstitudeofHandantointendtosetupthebuildinglocateatagroundofproceedingofinvestigatingwhatworkresultproceed.Analysethemainengineeringgeologicalproblem:thebuildingfoundationthatsetupthesmallerbaseindintinloadinginsoilinafoundationpressurelocateat，can'tmeetthedesignneeds，sohedemandproceedingthefoundationhandles.Accordingtoafoundationsoilengineeringgeologykind，cimbinedwithupperpartconstructioncharacteristics、foundationstabilityandearthquakeeffects.comingupwiththerockandsoilengineeringinvestigationreportandanalysingtheevaluatingthefoundationhandlestechniques.Aftercomparingdifferentmethodthenchooseoutthebestonewhichisthecementpowderashfromstovecrushedstonesstake，Make5kindsofhandlingproject，passingbyto5kindsofprojectsanalysiswiththeargument，comparingtochoose3kindsofoptimizationsproject.3kindsofprojectsthatcontrastselectproceededtheconcretedesignrespectively，fromactualconstruction.Selectingthebestprojecttousecementpowderashfromstovecrushedstonesstake.1KeywordsTheengineeringgeologyproblemTherocksoilengineeringinvestigatesEngineeringgeologicalanalysisGeotechnicalinvestigation;FoundationhandlestechniqueFoundationdesignCFGstakedesign2前言.....................................................................................................................3第1章区域概况.................................................................................................3第1．1节地理位置...................................................................................4第1．3节水文气象...................................................................................4第1．4节地层结构及岩性描述...............................................................5第1．5节区域地质构造...........................................................................6第2章场地工程地质条件.................................................................................7第2．1节地形地貌...................................................................................7第2．2节水文地质条件及水的腐蚀性评价...........................................8第2．3节地质构造...................................................................................9第2.4节不良地质现象..............................................................................9第2．5节场地与地基土的地震效应.......................................................9第3章岩土工程勘察.....................................................................................12第3．1节勘察依据的标准和文件.........................................................12第3．2节勘查的目的与任务.................................................................13第3．3节勘察纲要的策划与设计说明......
