| 摘 要： | 多洞室交叉处围岩力学状况目前国内外研究相对较少。文章以锦屏二级水电站3#引水隧洞三洞交叉段为工程背景,为了解交叉洞室对围岩的影响,进行了三维地质力学模型试验;通过两组试验,有效地揭露了交叉洞室间的相互影响,以及开挖与支护方法对围岩稳定性的影响。最后通过超载试验,确定了交叉洞室的破坏模式及其破坏过程;试验结果为指导施工提供了依据。

| Abstract: | Little research has been done on the mechanical conditions of rock surrounding multiple crossing tunnels.A three-dimensional geomechanic model test was performed in order to understand the impact of crossing tunnels on surrounding rock based on the section crossed by three caverns of the No.3 water tunnel in the Jinping hydropower station,revealing the interaction of crossing caverns and the impact of excavation and support methods on the stability of the surrounding rock.The failure mode and its process of... |
