摘要: 把菱形思维的理论运用在巷道的支护方式中,根据巷道的具体特征确立了支护方式的特征元,建立了符合巷道支护方式的物元模型。从不同的特征元出发,发散生成多个不同的支护物元,依据岩体力学的知识建立了支护的收敛条件。对生成的物元进行筛选,并运用FLAC进行数值模拟,最终确定最优的巷道支护方式。

Abstract: The rhombus thought is applied to the roadway support design.According to the specific feature of tunnel,the eigenelement of the supporting is determined,and the right matter element model for the supporting is established.From different feature units,many different supporting elements are diverged and generated.Based on the knowledge of rock mechanics,the convergence condition of roadway support is given to filter out the generated supporting element.And the FLAC software is also adopted to make the numerical simulation to finally determine the optimal supporting method.

Key words: Rhombus thought method, Matterelement model, Supporting element, Numerical simulation, Supporting method
