摘要
采用未开挖的数值模型进行承载力试验,并与理论解答进行对比,验证该数值试验的有效性。首先建立复杂精细化的三维数值模型,模拟隧道施工过程中围岩的应力变化与变形机理,开展相关的试验研究。
This paper adopts the excavation of thenumerical model of bearing test, and compared withtheoretical solution, verify the validity of the numericalexperiments. First establish complex three -dimensionalnumerical model of refinement, simulated the process oftunnel construction stress change and deformationmechanism of surrounding rock to carry out relatedexperimental research.
