膨胀土地区深基坑应急抢险加固设计及受力机理

摘要

According to the consolidation design for the emergency rescuing of some foundation pits projects in Chengdu areas, the paper illus-trates the stressed mechanism and checking effect evaluation of the portal row piles, points out the finite element analysis to avoid the biased as-sumption caused by simplified calculation with stricter theories, so as to provide some beneficial reference for similar engineering design.%通过成都地区某基坑工程应急抢险加固设计案例，阐述了门架式排桩受力机理及检测效果评价，指出采用有限元分析避免了传统方法为简化计算所作的某些有失偏颇的假定，理论上更为严密，以期为同类工程设计提供一些有益的参考。
