摘要
该文通过数值模拟试验的研究形式,使用ABAQUS(有限元数值计算软件)数据分析方法,进行不同水平应力对巷道围岩应力分布与变形特征影响模拟试验,详细分析半圆拱形巷道围岩在不同水平应力下,巷道围岩应力的分布与变形特征的影响,探索水平应力、垂直应力与巷道围岩稳定性之间的关系,从而为巷道围岩控制实际施工提供充分的数据支持与理论依据,优化半圆拱形巷道围岩的稳定性能。
This paper used the method of the numerical simulation, using the ABAQUS （calculation software of the finite element numerical） data analysis method, simulated the influence of the different levels of stress on the surrounding rock stress distribution and deformation characteristics, detailedly analyzed the distribution of surrounding rock stress and deformation features of the semi-circular arch tunnel under different levels of stress, explored the relationship between the horizontal stress, vertical stress and the stability of surrounding rock, so as to provided fully data support and theoretical basis for actual construction of roadway surrounding rock control, optimized the stability performance of semi-circular arched roadway.
