用深层搅拌法提高液化地基的抗液化能力

Adopting deep bed stirring method to enhance liquefaction resistance of liquefiable foundation

随着城市建筑用地日趋紧张以及对周围环境的影响 ,多层建筑液化地基常用的处理方法 (加密法、换土垫层法 )越来越受到制约。从深层搅拌法形成机理来看 ,对消除液化能力有限 ,但如果将建筑物基础形式的选择与深层搅拌桩布置方式结合起来进行考虑设计 ,则可提高液化地基的抗液化能力。

With crisis of land use in construction and the influence on the environment the use of common treatment methods for high rise building's liquefaction foundation is more and more limited. The ability of eliminating liquefaction resistance is limited regard from the principle of deep bed stirring method, but based on the comprehensive design of the selection of building foundation type and the arrangement of deep bed stirring pile the liquefaction resistance can be enhanced.
