摘要

    摘要
  • 摘要: 基于对结构性的研究和常规三轴试验，合理评价了土结构性变化规律，建立了考虑土体剪应力和球应力综合影响的应力比结构性参数并提出适用表达式，分析了该结构性参数与强度参数之间的关系。在边坡开挖过程中，土体结构性的变化将对土体强度参数产生影响，在此基础上，进行了考虑结构性变化的边坡开挖安全稳定性评价，同传统的不考虑土体结构性边坡开挖的评价方法进行了分析对比，结果表明：结构性的变化对边坡开挖及其稳定性有较大影响，当考虑土体结构性变化的影响时，边坡开挖后的安全系数小于不考虑结构性变化时的边坡开挖安全系数。
    Abstract: Based on the structural studies and a large number of tests, a reasonable evaluation on structural change rules of soils is given. The structural parameters considering the combined effects of shear stress and ball stress of soils as well as an applicable expression are proposed. The relations between the structural parameters and the strength parameters are analyzed. In the process of slope excavation, the structural change of soils will affect their strength parameters. The structural change should consider the safety of slope excavation. Compared with the traditional methods without considering structural soil slope, the results show that the structural change of soils in excavation has great impact on their stability, and the safety factor of the slope after excavation considering structural change is less than that without considering the structural change.
