根据水平荷载下Ｗｉｎｋｌｅｒ地基上弹性长桩的ｍ法幂级数解，对《建筑桩基技术规范》中计算桩基水平承载力的简化方法进行了讨论与修正，使该方法能考虑弯矩荷载的影响；并指出：当按变形控制计算桩基水平承载力时，《规范》对地基土水平抗力系数的比例系数ｍ值取值的规定是值得商榷的。 Based on the m-th power series solution of elastic long piles on Winkler foundation under horizontal loads, the simplified method for calculating the horizontal bearing capacity of pile foundations is discussed and modified to make it possible to consider the bending moment load. The impact; and pointed out: When calculating the horizontal bearing capacity of the pile foundation according to the deformation control, the provisions of the “standard” on the value of the ratio coefficient of the horizontal soil resistance coefficient of the foundation soil is worth discussing.
