某超高层建筑深基坑管井降水的应用与探讨

Well Point Dewatering Applications in the Deep Excavation of an Extra High-Rise Building

随着南通地区高层建筑的增多,深井降水利用较为普遍,某些深基坑在设计计算过程中未考虑降水深度范围内土层对降水的影响,易造成降水失败,结合具体工程,对深井降水方案进行分析和探讨,可供相关工程参考。

With an increase amount of high and extra high-rise buildings, the well point dewatering technics is widely utilized inthe construction in Nantong area. In some cases, the number and depth of the well points in were determined by the conven-tional dewatering analysis, but they were unsuccessful since the soil stratigraphy impact on the dewatering was not considered.This paper presents the suggestions and consideration in the deep dewatering well design and construction.
