摘要:
为了验证某国防隧道工程设计和施工方案的可行性.根据地下结构设计理玲和岩石屈服的Drucker-Prager准则,考虑到围岩的自身承栽能力,用ANSYS9.0软件对该隧道的开挖与支护过程进行三维有限元模拟,对设计参数进行验证,对周边围岩变形和初期支护效果进行综合分析,得出结论:该设计方案可行,初期支护满足要求,囤岩能够自行稳定.该数值分析结果与现场实测结果一致,可为相关工程设计和现场施工提供理论指导.
Abstract:
In order to verify the feasibility of a national defense tunnel engineering design and construction scheme. According to the Drucker-Prager criterion of underground structure design and rock yield, considering the self-bearing capacity of the surrounding rock, ANSYS9.0 software was used to simulate the excavation and support process of the tunnel in <>D finite element, verify the design parameters, and comprehensively analyze the deformation and initial support effect of the surrounding rock, and conclude that the design scheme is feasible, the initial support meets the requirements, and the hoard rock can stabilize by itself. The numerical analysis results are consistent with the on-site measurement results, which can provide theoretical guidance for related engineering design and on-site construction.
