本文提出了一种迅速设计巷道和地下结构支护的近似方法,它考虑了结构的几何尺寸和刚度的影响,用形变模量讨论围岩的性质,根据应力极限和最佳支护要求及断面尺寸的限制,以系统载荷量作为数据输入,直接进行设计。现在引入一个“当量岩柱”的概念用以模拟围岩。本文只详细论述了对围岩的分析,但也根据围岩性质,提出了标准支护设计所需的灵敏度分析结果,这些结果也涉及到许多经验设计方法。
In this paper, an approximate method of rapid design of roadway and underground structure support is proposed, which takes into account the influence of the geometry and stiffness of the structure. The deformation modulus is used to discuss the properties of the surrounding rock. According to the stress limit and the optimal support requirements, The size of the limit to the system load as data input, direct design. Now introduce the concept of “equivalent pillars” to simulate the surrounding rock. This article only discusses the analysis of the surrounding rock in detail, but also based on the nature of the surrounding rock, the sensitivity analysis results of the standard support design are proposed. These results also involve many empirical design methods.
