某软土地区深基坑开挖数值模拟分析

以某软土地区深基坑开挖为背景,运用有限元方法计算模拟了基坑开挖的不同阶段,分析不同工况下基坑及周围土体的变形和受力情况,并对不同施工方式下基坑变形和受力进行了对比分析。数值分析表明软土地区深基坑开挖时,需采取相应的施工措施,控制基坑变形和受力,确保工程安全顺利进行。研究结论可为类似工程提供借鉴与参考。

NUMERICAL SIMULATION OF DEEP PIT EXCAVATION IN SOFT SOIL

Based on the engineering practice of deep pit excavation in soft soil,the application of finite element method to simulate different construction stage of deep pit excavation is presented.The deformation and stress of foundation pit and surrounding soil are analyzed in details.Some conclusions have been drawn.The numerical analysis results show that different measures should be taken during the construction of deep foundation pits in soft soil to control the deformation and stress and assure the constructio...
