Abstract
In this paper,deformation monitoring at different positions of deep foundation pit of a subway line in Zhejiang Province was carried out.The results show that the settlement of foundation pit,the horizontal displacement of retaining wall,the vertical displacement of column piles and the settlement of surrounding buildings have certain fluctuations under different positions and different monitoring times,but the fluctuation range is small.The cumulative maximum settlement of foundation pit is only 5.7 mm.The cumulative maximum horizontal displacement of diaphragm wall is 15 mm.The cumulative maximum vertical displacement of the column pile is 14.2 mm.The cumulative maximum surrounding building settlement is 11.3 mm;The accumulated value and monitoring variation coefficient of each position meet the standard requirements,which proves the safety and reliability of the deep foundation pit project.关键词
