摘要
以南宁轨道交通一号线广西大学站基坑工程为背景,应用FLAC3D数值模拟软件建立了圆砾地层深基坑三维模型;通过计算得到了圆砾地层基坑围护结构和周围地表的变形规律,计算结果表明,FLAC3D软件和Mohr-Coulomb模型比较适用于南宁地区圆砾地层的地质条件,若参数选取准确,能够比较准确的模拟基坑开挖的全过程。
Taking foundation pit project of Guangxi University station of Nanning track traffic first line as the background,this paper established deep foundation pit 3D model using FLAC3D numerical simulation software,through the calculation gained the deformation law of round gravel stratum foundation pit retaining structure and surrounding surface.The calculation results showed that,the FLAC3D software and Mohr-Coulomb model were suitable for the geological conditions of round gravel stratum Nanning region,if the parameters were accurately selected,could more accurately simulate the whole process of foundation pit excavation.
