围岩破坏 meaning in Chinese
surrounding rock failure
Examples
- Analysis on destruction reason of deep roadway host rock and its proventive technique
深部巷道围岩破坏机理分析与防治技术 - Study on failure laws of surrounding rock in the steep dip and extra - thick coal seam mining
急斜特厚煤层开采围岩破坏规律研究 - On the study of tunnel excavation , physical simulation can effectively simulate the nonlinear characteristics during failure of surrounding rocks
在隧道开挖问题研究中,物理模拟能有效地模拟围岩破坏过程中非线性特征。 - Abstract : based on the analysis of the main causes of stope chute failure , flac3d numerical calculation software is used in the systematic study of the mechanical state of the surrounding rock before and after the chute reinforcement from the aspects of the stress distribution of rock mass , the plastic fractured region and the movement of rock mass so as to disclose the fracture mechanism of the surrounding rock and the mechanical system of the reinforcement engineering
文摘:在分析造成采场溜井破坏的主要原因基础上,应用flac3d数值计算软件,从岩体应力分布、塑性破坏区和岩体移动等方面,系统研究了溜井加固前后的围岩力学状态,揭示了围岩破坏机理和加固工程的力学机制。 - It is found that the rational located destressing boreholes can induce structural failure of the surrounding rock - mass , consequently the high stress move deeply in the rock - mass , and the stress environment in the surrounding rock is ameliorated , the spatio - temporal order of the destruction of the surrounding rock - mass is changed when the destressing boreholes and bolting net with wire mesh composite support are accomplished , therefore the compound supporting technology has prominent advantage for control the deformation and destruction of the surrounding rock
模拟发现:合理布置的卸压孔可以导致巷帮围岩的结构性预裂破坏,从而使围岩高应力向深部转移;在卸压孔和锚网联合支护后改善了围岩附近的应力环境,改变了围岩破坏的时空次序,对控制围岩变形和破坏具有突出的优越性。
