摘要： 随着城市地下空间的开发利用，超大深基坑的建设越来越多。超大深基坑由于工期较长，特别是在南方地区的梅雨季节，在施工过程中不可避免的会受到外界因素及其周边环境的影响，从而影响深基坑的稳定性。依托现场监测资料，分析了连续降雨及钻孔桩间渗漏的发生对基坑稳定性及其临近建筑物的影响规律，可供端头井的施工参考。

Abstract: The construction of large deep excavations become more and more frequent with the development of utilizing the underground space in the urban area. With relative long construction duration, adverse effects from the external and adjacent environment on the large deep exaction projects are inevitable. This is especially true for the prolonged precipitation season in Southern China, the stability of the excavation is often affected by the rainfalls. Based on the construction monitoring data, this paper presents the effect of the long duration rainfall and the leakage among drilled piles on the stability of the excavation and adjacent buildings.
