摘　　要：采用有限元方法对土体的应变场进行分析,另外采用弹性力学的方法对土钉受力以及应变情况进行分析,在此基础上得出求解土钉轴力的一种方法,并结合实例对此方法进行验证。This paper adopted FEM to calculate the strain field of the ground near a foundation pit, and employed Mindlin Solution to analyze the influnce of soil nails. Then after combining the strain caused by the 2 factors, a method to determine the axial force of soil nails was established. An example was put forward at the end to verify the method.
