| 摘 要： | 通过对出海闸的整体有限元数值计算(计入复合基础的底板、桩与土的共同作用),计算其结构的位移场及应力场.结论是复合基础底板与单一基础底板的内力、位移在大小、分布、控制工况及危险点上完全不同.由于桩基对底板的作用,基础底板出现应力集中为该复合基础的明显特征.

| Abstract: | By the numerical simulation of integrate finite element for the sluice, which included the combined action between the compound foundation slab, the pile and soil,the displacement field and stress field of the structure are obtained. It is concluded that the internal force, distribution, working condition of control, and dangerous point for couposite foundation are different from those of single foundation. Owing to the action of pile to the foundation slab, the severe stress concentration of the foundation slab are the apparent characteristics of composite foundation. |
