Settlement Observation and Data Analysis of Deep Foundation Pit Engineering of Industrial Plant
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.
