摘要
考虑复合桩基极限状态时条形承台下土体的可能破坏特点,将土体的塑性变形分为竖直向的整体滑动和水平向的绕桩流动。根据极限分析法上限定理,分析上述因素对条形承台复合桩基的极限承载力的影响,给出圆桩时承台下地基土极限承载力的上限理论解。
Based on the possibly destructive features of soils under strip composite pile foundations on the ultimate state, plastic deformation is divided into vertically whole sliding and horizontally sliding around a pile. According to upper limit theorem and analyzing the contribution of the above factors to the ultimate resistance of strip composite pile foundations, the upper theoretical solution for the ultimate resistance to the soil under caps of circular piles in put forth.
