Embodiment 1
[0080] see Figure 1 to Figure 15 , a calculation method for the ultimate bearing capacity of a strip foundation foundation under the action of an inclined load includes the following steps:
[0081] The first step is to establish a multi-rigid block foundation failure calculation model.
[0082] Rigid rough strip foundation width is B 0 , the overload on both sides is q, assuming that the ultimate bearing capacity of the foundation at the load inclination angle δ is P u Under the action of , the foundation soil appears one-sided translation failure, and the foundation failure model can be expressed as a failure body composed of (n+1) triangular rigid blocks, such as figure 1 shown. The triangular rigid block ABC is rigid block No. 0, and then the remaining rigid blocks are numbered 1, 2,..., n from left to right. The position of the ground failure slip surface is controlled by a group of matrix variables, and its mathematical expression is shown in formula (1).
