【摘要】 介绍了南京某超高层建筑深基坑开挖的周围环境监测结果 ,分析了该深基坑开挖所引起的环境问题 ,包括地下水水位下降、建筑物和土层变形和裂缝 ,得到了一些有益的结论。认为基坑地质条件较好且开挖满足支护系统安全稳定的条件时 ,仍可能对周围环境造成较大的影响更多还原

【Abstract】 A case study on monitoring environmental impact of a super-building deep excavation in Nanjing City is introduced in this paper. It analyzes the environmental influence of deep excavation on surroundings, including groundwater table descent, buildings and soil layers deformation and cracks,and obtains some useful conclusions. It also indicates that deep excavation may greatly affect the surroundings though engineering geology conditions are fine and the supporting systems are safe.更多还原
