在现场进行不规则岩块的点荷载试验,是获得强度指标最简单、最有前途的方法,也可以获得岩石的抗拉、抗压强度。 本文通过五种典型形状的岩块(近球体、椭球体、长方体、多棱体和四面体)的有限元计算和分析,探讨了不规则岩块在点荷载作用下的应力分布规律,得到除四面体(极少)以外,其余四种形状的应力分布规律均极为相似。 Performing a point load test of irregular rock masses in the field is the simplest and most promising method for obtaining strength indexes, and also can obtain the tensile and compressive strength of rocks. In this paper, finite element calculation and analysis of five typical rock masses (near spheres, ellipsoids, cuboids, polyhedrons, and tetrahedrons) are used to investigate the stress distribution law of irregular rock masses under point load. Outside the tetrahedron (rare), the stress distribution of the other four shapes are very similar.
