摘　　要：在岩土工程勘察与设计过程中,经常遇到地基土液化问题,该问题对工程安全、建设投资有较大影响。在众多抗液化措施中,桩基是一种常用方法。结合相关规范和工程实例,介绍了地基土液化的概念;又以云南开远市某桥梁工程钻孔灌注桩为实例,介绍了处理措施及桩基处理地基土液化的设计要点。In the course of geotechnical engineering reconnaissance and design,the problem about liquefaction of foundation soil is often encountered.This problem has great influence on the engineering safety and construction investment. In many measures against liquefied foundation, the pile foundation is a commonly used method. According to related specifications and some bridge engineering cast-in-situ bored pile project in Kaiyuan,Yunnan,this paper introduces the concept and treatment measures of liquefaction of foundation soil and some design key points for pile foundation in treating liquefaction of foundation soil.
