摘要
运用现代支护结构原理,结合工程实例,通过ANSYS软件进行了开挖和支护的数值模拟,计算出了支护结构的内力,由其内力结果,得出衬砌强度安全系数,研究不同厚度的衬砌对其安全系数及其稳定性的影响,根据工程规范,确定衬砌的最小安全厚度。
Using morden supporting structure theory, this paper does numerical analysis of excava- ting and supporting with the software ANSYS in an engineering project, and calculate the internal force of supporting structure. Through the analysis results of internal force, the safety factor of the strength of the lining can be obtained. According to the engineering specification, it can determine the minimum safety thickness of lining by studying how thickness of lining affects the safety factor and stability.
