The method which is used to measure and compute moment, yield and turning angle by steel bar gauge is introduced in detail. According to the measuring results, the horizontal critical load of the testing pile is 120 kN. The steel bar gauge measuring results show that the largest moment is located in the depth from 2 m to 3 m under the horizontal load, it transfers to the deeper location with the increase of the horizontal load, and the bend distortion only occurs in the upper of 1/3 pile length.

结合实际工程详细地介绍了利用钢筋计测试水平荷载作用下桩身弯矩、挠度和转角分布的方法，根据桩顶位移和钢筋内力测试结果判定试验桩的水平临界荷载为120 kN；根据钢筋计测试结果可知，在水平荷载作用下，桩身最大弯矩截面位于在地面以下2～3 m处，且随着荷载的增大最大弯矩截面逐渐向深部转移；发生弯曲变形的部分主要是桩长1/3以上的桩体，而其下的桩体几乎不发生变形。

For composite foundation with compressible piles, based on displacement harmony condition, and combining with load transfer method and approximate solution of differential equation, analysis methods of linear and nonlinear interaction between piles and surrounding soil were suggested. A lot of significative results, for example availability pile length, load distribution between piles and surrounding soil, load distribution among all piles under rigidity pile-cap, load-settlement relation etc, were obtained.
