摘要 应用荷载传递法推导出了单桩的柔度系数 ,在此基础上推出了两桩及桩土相互作用的柔度系数 ,并与有限元法进行了比较 。 The flexibility factor equation of single pile was deduced.On this base,interaction factors of two piles and pile and soil were given.Some examples were computed using the method and curves of flexibility factor presented.Compared with FEM,the present method is of high precision and practicability.
