Measures for Liquefiable Soil Layers in the Foundation Surrounding Underground Building Structures

　　地下建筑结构周围地基存在液化土层时，应采取下列措施：
　　1、对地基采取注浆加固和换土等措施消除或减小地下结构上浮的可能性。当未采取消除液化措施时，应考虑增设抗拔桩使其保持抗浮稳定。
　　2、位于液化地基中的地下建筑结构的桩基，应同时满足抗拔桩的设计要求。
　　3、地下建筑结构与薄层液化土层相交时，可不做地基抗液化处理，但应通过计算适当加强结构，并在结构承载力及其抗浮稳定性的验算中考虑土层液化的影响。
　　4、施工中采用深度大于20m的地下连续墙作为围护结构的地下建筑结构遇到液化土层时，可不做地基抗液化处理，但其承载力及抗浮稳定性的验算应考虑外围土层液化的影响。
