摘要
基于Duncan-Chang E-B模型理论及平面应变状态堆石料的内摩擦角经验表达式,通过大量试验数据分析研究提出通过堆石料岩块的抗剪断内摩擦角估算堆石料的内摩擦角、切线模量的关系式,进而通过相关公式进一步求解剪切模量、体积变形模量,通过工程实践检验是可行的。
Based on Duncan-Chang E-B model theory and the internal friction angle experience expression of plane strain state of rockfill and through analysis of a large number of test data, this paper proposes the relational expression of using the shear angle of internal friction of the pile of stone block to estimate the internal friction angle and the tangent modulus of the rockfill material, and then solves the shear modulus and bulk deformation modulus with relevant formula. Engineering experiments shows that it is feasible.
