基于FLAC^(3D)白荡湖闸站基坑边坡变形和稳定分析

Deformation and stability analysis of foundation pit excavation slope of Baidanghu sluice station based on FLAC^(3D)

文章以枞阳县白荡闸改扩建基坑开挖为研究对象,通过数值模拟的方法,综合分析基坑边坡的变形与稳定性,对比不同边坡坡比的数值计算结果,结合相关规范的规定,最终确定1∶2的坡比方案为最优。

Taking the foundation pit excavation of the reconstruction and expansion of Baidang gate in Zongyang County as the research object,this paper comprehensively analyzes the deformation and sta-bility of the foundation pit slope through the method of numerical simulation,compares the numerical calculation results of different slope ratios,and finally determines that the 1:2 slope ratio scheme is the best.
