各种理论的比较本文上一节讨论了桩基性能的各种分析方法,均是采用边界元法的单网格系统。值得注意的是,为确定计算出的结果对所采用方法的灵敏性,比较这些方法是有意义的。同时,将这些方法与有限元法等分析方法分别进行比较就更有意义。因此,本节将对下列三个不同的问题进行这种比较:(a) Comparison of various theories This previous section discussed various methods for analyzing the performance of pile foundations, all of which are single-grid systems using the boundary element method. It is worth noting that it is meaningful to compare these methods in order to determine the sensitivity of the calculated results to the methods used. At the same time, it makes more sense to compare these methods with analysis methods such as the finite element method. Therefore, this section will make this comparison for the following three different issues: (a)
