刚性基础底部摩阻力对基础顶面及墩顶面的位移有显著影响,其值可将基底承压力与摩擦系数(f=tanφ)相乘而得。当摩阻力很大且满足以下条件时 ((n+1)H+(n+3)M/h-2fN)/((n+1)(n+2)(n+3)(H+fN))≤K_n/(ah)~(n+3)≤((n十1)H+(n+3)M/h+2fN)/((n+1)(n+2)(n+3)(H-fN))支立于非岩石地基上的基础可按基底嵌入岩层内考虑,文中还介绍了这两种支承情况时基础顶面位移的差值。
The base friction at the rigid foundation has a significant effect on the displacement of the foundation roof and the top of the pier, and its value can be obtained by multiplying the bearing pressure of the foundation by the friction coefficient (f = tanφ). (N + 1) H + (n + 3) M / h-2fN) / (n + 1) (n + 2) (n + 3) (H + fN) when the frictional resistance is large and the following conditions are satisfied: ) ≤ K_n / (ah) ~ (n + 3) ≤ (n + 1) H + (n + 3) M / h + 2fN) / (n + 1) (n + 2) (n + 3) H-fN)) Based on the non-rock foundation foundation can be embedded into the rock into consideration, the article also introduced the two kinds of bearing the basis of the top surface displacement difference.
