摘要
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。
Based on the engineering practice of deep pit excavation in soft soil, through the finite element method to simulate the deformation and stress of foundation pit and its surrounding soil in different construction stage of deep pit excavation. The deformation and stress of foundation pit and surrounding soil are contrasted and analyzed in different construction modes. The numerical analysis result shows that the corresponding measures should be taken during the construction of deep foundation pits in soft soil to control the deformation and stress and assure the construction safety. The experience and conclusions presented can be referred in the design, construction and site monitoring of similar tunnels.
