隧洞岩爆机制物理模型试验研究

An Experimental Study on Rockburst Mechanism around Tunnils by Physical Simulation

详细介绍了模型试验研究的构思、模型材料研制、试验研究步骤及结果,并在分析成果的基础上,对岩爆发生的环境条件,发生的过程、现象和机制进行了探讨。文中还介绍了有限元分析,证明该试验与计算结果吻合较好。模型中再现的破坏机制与天生桥隧洞中的实际情况相同。

The principle, simulating materials, procedures and results of a simulating test are introduced, and based on it, the environmental condition, process, phenomenon and mechanism are. studied for the outbreak of rockburst. The analysis results obtained by using FEM are also presented. It is shown that the test results are correspondent well with the numerical ones, and that the failure mechanism discovered bY the test is the same as the situationof tunnels in Tian Shengqiao Hydroelectric Project in China.
