基于图解法的完整岩体破裂后碎胀变形研究

Research on the Deformation of Broken and Inflation of Broken Complete Rocks Based on Graphical Method

用图解的方法直观明了地解释和分析了岩体破坏后体积膨胀及岩块间的结构效应,结果表明:破裂后的岩块形成大小不等、形状各异的小岩块,其间接触方式有面接触和线接触2种,形成的承载结构呈稳定—失稳—稳定周期性变化,其承载能力越来越小。

The graphic method is adopted to explain and analyze volume expansion of broken complete rocks and the structure effects between the rocks. The research results show that,the little rocks of different sizes and shapes of broken complete rocks are acquired. Surface and line contact are the two kinds of contact modes. The bearing structure is stability,instability,stability periodic changes,and the its bearing capacity is more and more small.
