块体理论是近十几年来发展和完善起来的一种适合于裂隙岩体稳定性分析的行之有效的工程方法,其研究方法已经较为成熟。但是目前的研究都是建立在其基本假设,即结构面完全贯通的基础上的。而实际岩体中结构面并非呈完全贯通的空间展布,这样必然使研究结果偏于保守,造成相应支护措施等的加大,造成不必要的浪费。本文以内蒙古黄河特大桥边坡为例将岩桥思想引入块体理论当中,介绍了连通率的确定方法并推导了稳定性计算公式。
Block theory is an effective engineering method that is suitable for the stability analysis of fractured rock mass developed and perfected in recent ten years. The research methods have been mature. However, the current research is based on its basic assumption that the structural plane is completely connected. However, the actual rock mass structure surface is not completely through the space distribution, so inevitably make the research results more conservative, resulting in the corresponding support measures such as increased, resulting in unnecessary waste. In this paper, the rock bridge thought is introduced into the block theory by taking the Huanghe Super Bridge slope in Inner Mongolia as an example. The method of determining the connectivity rate is introduced and the formula of stability calculation is derived.
