中文摘要:随着基坑的开挖,当基坑的土压力减小到一定程度时,承压水的水头压力将大于基坑底土体浮重力,形成管涌、侧涌等现象,造成地基土上浮开裂。针对深层承压水的隔断技术措施,结合上海三至喜来登酒店基坑工程的特点,分析讨论了超深搅拌桩在隔断深层承压水的应用效果,对于今后类似工程的建设具有一定的参考和指导作用。

Application of Ultra-deep Cement-soil Mixed Pile in Deep Confined Water Partition Project
Abstract:With the excavation of foundation, when the earth pressure of foundation reduced to a certain extent, the head pressure of confined water will be greater than float gravity of soil at the bottom of foundation pit associated with piping formation and side gushing and so on, resulting in floating and cracking of soil. Based on deep confined water partition technique, according to the characteristics of the foundation of Shanghai Sanzhi Sheraton Hotel, application effect of ultra-deep cement-soil mixed pile in deep confined water partition project were analyzed and discussed, which could be the reference and guidance for the similar projects in future.
