A. 桩基和深基础：采用桩基时，桩端深入液化深度以下稳定土层中的长度，按计算确定，且对碎石土、砾、粗、中砂，坚硬黏性土和密实粉土不应小于0.5m，对其他非岩土不宜小于1.5m。采用深基础时，基础底面应埋入液化深度以下的稳定土层中，其深度不小于0.5m
B. 强夯法：强夯法根据不同土质条件和夯击能，可处理4～10m深度范围
C. 加密法：包括振冲法、砂石桩法和强夯法等，应处理至液化深度下界，采用振冲法、砂石桩法加固后，桩间土的标贯击数应大于液化判别标准贯入击数临界值
D. 换填法：用非液化土替换全部液化土层。液化地基土的处理范围，采用加密法、强夯法或换土法，在基础边缘以外的处理宽度，应超过基础底面下处理深度的1/2且不小于基础宽度的1/5
