摘要:
针对水平受荷桩刚度系数的传统计算公式复杂、计算量大的缺点，使用桩顶嵌固的边界条件推导出水平受荷桩刚度系数新的表达式。采用幂级数证明了新解法与传统方法是等价的，并通过算例验证了两种方法得到的刚度系数是相同的。对刚度系数的影响因素分析表明，桩径对刚度系数影响较大，其中水平刚度系数近似按桩径的两次方进行增长，转动刚度系数近似按桩径的三次方进行增长。土体m值对刚度系数也有一定的影响，其中水平刚度系数按m值的0.6次幂进行增长，转动刚度系数按m值的0.4次幂进行增长。
Abstract:
For the design of horizontal piles, the traditional expression for calculating the stiffness coefficient is too complex, and needs a lot of computation. A new expression for the stiffness coefficient of horizontally-loaded piles was derived by using the boundary conditions of pile top embedding, which reduced a lot of computation. The new method was proved equivalent to the traditional method by power series, and an example was given to verify that the stiffness coefficient obtained by the two methods showed no difference. Analysis of the influencing factors of the stiffness coefficient showed that pile diameter had great impact on the stiffness coefficient, the horizontal stiffness coefficient increased approximately by the square of pile diameter, and the rotational stiffness coefficient increased almost by the cube of pile diameter. The m value of soil also had certain influence on the stiffness coefficient, i.e., the horizontal stiffness coefficient increased by 0.6 power of the m value, and the rotational stiffness coefficient increased by 0.4 power of the m value.
