摘要:

由于地质赋存环境的不同,深埋与浅埋洞室在开挖后将产生不同的变形规律. 本文基于有限差分计算软件FLAC3D,数值模拟了深埋与浅埋软岩洞室随应力边界条件、岩石力学性能、洞室断面形状等因素变化的变形特点. 计算结果将对洞室的选型与开挖支护等提供参考.

Abstract:

Due to the difference of their environments, the deep and shallow buried tunnels show different deformation patterns in the excavation. This paper simulates the deformations of the deep and shallow buried soft rock tunnels with different stress boundary conditions, rock mechanical properties and section shapes of tunnels. The calculation results might be used for the selection of the tunnel section shapes, and the excavation support of tunnels.

Key words:
