摘　　要：在桩身中安装钢筋应力计,可以观察钢筋的应力变化,从而得到桩身的受力性能和承载力以及计算出桩身的侧摩阻力等.工程实践中经常遇到两种计算桩身轴力的公式,这两种计算公式的推导过程以及这两种方法的优缺点,并以某工程钻孔灌注桩桩身轴力监测为背景,指出哪种方法计算桩身轴力是合理的、可行的,旨在为桩的轴力计算提供依据.This paper introduces the stress variation by installation of reinforcement stress-count in pile to inquire the axial stress, hearing capacity and side friction of the pile. The two methods of calculation of pile axial stress in the engineering practice are analyzed, and compared, the processes of the two different formula, as well as the advantages and disadvanta- ges of two methods are discussed theoretically. Based on the monitoring of a cast-in-situ pile axial force, a more reasonable and feasible method is pointed out for pile axial force calculation.
