摘　　要：为提高桩的水平力计算精度,提出了地基反力系数按双参数抗力模式表达下的反力积分法数值分析方法,并详细推导了计算公式。基于这些公式,编制了相应的计算程序。算例表明该方法计算精度高,可使数值解接近真实解。In order to enhance the calculation precision of internal force of laterally loaded pile, the author in the paper proposes a method calculating internal force and displacement of laterally loaded pile. The method is presented which the composite stiffness of the pile and soil and its bipaprameter of foundation coefficient can be back calculated by the fruit of analytical method. The displacements and internal forces of laterally loaded pile can be calculated by means of reaction integration method that the principle is simple and easily to be programmed. The examples show the method to be convenient and reliable.
