The Influence of Underground Continuous Wall Construction of Deep and Large Foundation Pit on Existing Building
Based on the project of China Economic and Cultural Research Center in Handan Campus,this paper systematically introduces the support scheme and construction technology of underground continuous wall.The settlement of different parts of the surrounding buildings during the construction of the underground continuous wall is obtained through on-site monitoring.The research shows that the influence of different stages of underground continuous wall on surrounding buildings is significantly different.Among them,the influence of trenching pouring stage is the largest,the influence of guide wall construction stage is the second,the influence of excavation construction stage is the third,and the influence of dewatering construction stage is the smallest.The settlement of monitoring points B and E is generally large,and the settlement of these two parts should be monitored emphatically during the construction process.
