一、m法用于桩基空间图式的计算《铁路标准设计通讯》1972年第7期“桥梁墩台基础考虑土壤弹性抗力的计算”(以下简称“计算”)一文中的m法(目前大家都这样叫它,本文也这样简称它),不仅适用于外力作用平面内带有斜桩的桩基,而且适用于带有双向斜桩并承受双向外力、力矩和扭矩的桩基。对于这种空间受力的桩基,每一根桩的桩顶轴向力、横向力和弯矩以及承台座版底面的线位移和转角均可按“计算”一文的原理求得,其基本公式与《铁路桥梁桩基设计》(1964年,第二版)第152-187页的公式完全相同。这就说明该书所介绍的空间图式的计算
First, the m method for the calculation of pile foundation spatial pattern “Railway Standard Design Communication” 1972 the seventh period “bridge abutment foundation consider the calculation of soil elastic resistance” (hereinafter referred to as “calculation”) one article m law (currently Everyone calls it this way, but it is shortened to this article.) It applies not only to piles with inclined piles in the plane of action of external forces, but also to piles with two-way inclined piles that can withstand bi-directional external forces, moments and torques. For such space-stressed pile foundation, the axial force and lateral force of pile top and the line displacement and rotation angle of the bottom of each platform can be calculated according to the principle of “calculation”. The basic The formula is exactly the same as the formula on pages 152-187 of “Design of Railway Bridge Pile Foundation” (1964, second edition). This explains the calculation of the spatial schema introduced in this book
