摘要
文中以浙江温州某工业厂房为例,设计合理监测方案对基坑深层水平位移、坡顶沉降量、坡顶水平位移、地下水位及周边地表沉降量进行连续监测.结果表明,基坑累计坡顶沉降量时程响应曲线快速增加阶段的日位移速率约为0.08 mm/d,缓慢增加阶段的日位移速率约为0.008mm/d;基坑累计周边地表沉降量快速增加阶段的日位移速率约为0.2 mm/d,基坑地下水位累计下降量快速增加阶段的日位移速率约为6.25 mm/d;所有测点的数据均未达到设计的预警值,各个变形的日变化速率均相对较小,证实该基坑支护工程安全可靠.
Abstract
Taking an industrial plant in Wenzhou,Zhejiang Province as an example,a reasonable monitoring scheme was designed to continuous-ly monitor the deep horizontal displacement of foundation pit,the settlement of the slope top,the horizontal displacement of the slope top,the groundwater level and the surrounding surface settlement.The results show that the daily displacement rate is about 0.08 mm/d in the stage of rapid increase and about 0.008 mm/d in the stage of slow increase.The daily displacement rate is about 0.2 mm/d in the stage of rapid increase of accumulated surface settlement around the foundation pit.The daily displacement rate is about 6.25 mm/d in the stage of rapid increase of the cumulative decrease of foundation pit groundwater level.The data of all measuring points have not reached the designed warning value,and the daily change rate of each deformation is relatively small,which confirms the safety and reliability of the foundation pit supporting project.
