1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.2KeywordsTheengineeringgeologyproblemTherocksoilengineeringinvestigatesEngineeringgeologicalanalysisGeotechnicalinvestigation;FoundationhandlestechniqueFoundationdesignCFGstakedesign3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.................................................13第2.3节工作量完成情况.....................................................................15第4章各层土的物理力学指标统计............................................................16第3.1节统计步骤....................................................................................16第3.2节计算方法....................................................................................16第3.2节原位测试数据.........................................................................17第3.3节土层物理力学指标评价.........................................................19第五章岩土工程分析评价...........................................................................19第4.1节分析评价的内容及要求.........................................................19第4.2节场地稳定性和适宜性评价.....................................................19第4.3节地基均匀性分析与评价...........................................................19第4.4节可能出现的岩土工程问题.......................................................20第4.5节地基承载力确定与地基强度评价.............................................21第4.6节地震效应分析与评价................................................................22第六章基础设计及论证.................................................................................24第1节概述.............................................................................................24第5.2节地基与基础方案设计分析........................................................25结论与建议.........................................................................................................27结束语.................................................................................................................284前言受邯郸市从台区东升企业总公司(甲方)的委托,我院承担了其拟建邯郸市新时代广场的岩土工程勘察工作。各拟建工程设计情况详见拟建工程一览表。各拟建建筑物的形状及尺寸详见“勘探点平面布置图”。拟建工程设计情况一览表工程名称建筑主体层数(层)建筑高度(m)结构类型地下室层数基础情况基础形式基础尺寸m*m基础埋深(m)基底压力KPa主楼2796.9框架剪力墙3桩基+筏板32.6*32.616.3480群楼833.3框架剪力墙3筏板32.6*20.016.3130地下车库————框架剪力墙3筏板——16.360依据《岩土工程勘察规范》第3.1.1—3.1.3条之规定,本拟建工程的重要性等级为一级(即重要工程);场地复杂程度等级为二级(即为中等复杂场地);地基复杂程度等级为二级(即为中等复杂地基)。按此规范第3.1.4条综合评价,岩土工程勘查等级为甲级。拟建工程主楼为地上27层,群楼8层(局部5层),并有外延的地下车库,地下均为3层,按照《建筑地基基础设计规范》第3.0.1条之规定,高层超过10层,且有三层地下室,故可将本拟建工程的地基基础设计等级定为甲级。第1章区域概况第1.1节地理位置场地位于邯郸市市区中东部,北与人民路相临,东与黎明大街相临,西侧靠近保
