摘　　要：概述了低应变反射波法的基本原理、基本假设,结合工程实例分析桩周土阻力对低应变检测结果的影响,得出结论:当地质条件较好时(桩周为粉质粘土、强风化凝灰岩、卵石土、强风化花岗岩)有效检测桩长远小于40 m,并有针对性的提出了相应的建议。The basic principles and assumptions of low strain reflection method are summarized,and the influence of soil resistance on low strain detection results is analyzed based on engineering examples. It is concluded that the effective test piles are less than 40 m long term when the local quality conditions are better（silty clay,strong weathering tuber,pebble earth and strong weathering granite）,and the corresponding suggestions are put forward.
