FLAC3D软件在基坑开挖模拟及支护改进的应用

APPLICATION OF FLAC 3D SOFTWARE IN FOUNDATION PIT EXCAVATION SIMULATION AND SUPPORT IMPROVEMENT

在基坑工程施工中,保证开挖全过程基坑自身结构的安全性和稳定性尤为重要。以工程实例为依托,利用基础数据,结合FLAC 3D仿真计算软件,对基坑进行了建模和数值计算,进一步研究了基坑开挖过程中地基和基础的应力变形特性和沉降的变化。综合分析结果表明,数值模拟与工程实际基本吻合,能够在施工前很好地反映出现场情况。

In the construction of foundation pit engineering,it is particularly important to ensure the safety and stability of the whole process of excavation.Based on engineering examples,this paper used basic data and FLAC3D simulation software to conduct modeling and numerical calculation of foundation pit,and further studied the stress deformation characteristics and settlement changes of foundation and foundation in the process of foundation pit excavation.The comprehensive analysis results show that the numerical simulation is basically consistent with the actual project,and can reflect the site situation well before construction.
