摘要
采用FLAC3D程序,以小浪底工程为背景对其开挖过程在多因素影响下进行了大量计算工况的二维数值模拟。对毛洞开挖主厂房边墙关键点最大水平位移进行了系统分析,包括相对位移与相对载荷、埋深及弹性模量之间关系的分析,可供大型地下洞室群稳定分析时作参考。
The excavation process of underground cavern groups is simulated with the example of Xiaolangdi Project by using FLAC3D program, in which different influencing factors are considered. System analysis of the horizontal displacements of the key point of side wall, including the relationships between relative displacements, relative loads, embedded depth and elastic modulus, is carried out. These will provide reference for the study of large-scale underground cavern groups.
