基坑变形监测方案VIP免费

摘要本设计主要针对某深基坑工程施工过程中基坑变形及引起周边环境变形进行监测的方法及相关数据处理方案的设计与分析。主要监测内容对基坑壁进行水平位移监测和沉降监测；内支撑格构柱进行沉降监测；周边临近基坑受基坑影响的建筑物作沉降监测；周边建筑沉降超预警值后要求进行倾斜观测。采用监测方法为精密二等水准、极坐标法、投点法，并对其可行性进行做了精度分析。关键字：沉降观测；水平位移观测；倾斜观测；二等水准；极坐标IAbtractThisdesignismainlyforadeepfoundationpitduringtheconstructionoffoundationpitdeformationandcausethedeformationofthesurroundingenvironmentmonitoringmethodsanddataprocessingprogramdesignandanalysis.Themainmonitoringcontentofthefoundationpitwallformonitoringhorizontaldisplacementandsettlementmonitoring;Insupportoflatticecolumnforsubsidencemonitoring;nearanexcavationfoundationpitsurroundingbyeffectofbuildingsforsubsidencemonitoring;Thesurroundingbuildingsettlementofsuperearlywarningvaluerequirementsofthetiltobservation.Themonitoringmethodforprecisiontwolevel,thepolarcoordinatemethod,pointsmethod,Anditsfeasibilitywasmadeprecisionanalysis.Keyword:Horizontaldisplacementobservation;settlementobservation;tiltobservation;twolevel;polarcoordinatesII安徽建筑工业学院毕业论文目录目录摘要................................................................................................................................................I............................................................................................................................................................Abtract..............................................................................................................................................II1工程概况......................................................................................................................................12监测目的......................................................................................................................................23编制依据......................................................................................................................................34控制点和监测点的布设...............................................................................................................44.1变形监测基准网的建立.....................................................................................................44.2监测点的建立.....................................................................................................................44.3监测级别及频率.................................................................................................................55监测方法及精度论证...................................................................................................................65.1水平位移观测方法.............................................................................................................65.2沉降观测方法.....................................................................................................................85.3基坑周围建筑物的倾斜观测.............................................................................................96成果提交....................................................................................................................................107人员安排及施工现场注意事项...............................................
