基坑變形監(jiān)測方案

1、I摘要本設(shè)計主要針對某深基坑工程施工過程中基坑變形及引起周邊環(huán)境變形進行監(jiān)測的方法及相關(guān)數(shù)據(jù)處理方案的設(shè)計與分析。主要監(jiān)測內(nèi)容對基坑壁進行水平位移監(jiān)測和沉降監(jiān)測；內(nèi)支撐格構(gòu)柱進行沉降監(jiān)測；周邊臨近基坑受基坑影響的建筑物作沉降監(jiān)測；周邊建筑沉降超預(yù)警值后要求進行傾斜觀測。采用監(jiān)測方法為精密二等水準(zhǔn)、極坐標(biāo)法、投點法，并對其可行性進行做了精度分析。關(guān)鍵字：關(guān)鍵字：沉降觀測；水平位移觀測；傾斜觀測；二等水準(zhǔn)；極坐標(biāo)安徽建筑工業(yè)學(xué)院畢業(yè)論文目錄
