【摘要】 在现场调研和工程地质勘察的基础上,分析了高句丽将军坟变形破坏的特征,应用三维有限差分程序FLAC3D,模拟研究了高句丽将军坟分别在自重、局部地基软化和地下水渗流3种工况下的应力场变化和变形破坏规律,揭示了高句丽将军坟渐进变形破坏的机制:以软弱地基的固结压密为先导,继而引起坟体倾斜沉陷,造成地基隆起、块石间位错张开,最终导致高句丽将军坟变形破坏的过程。研究结果对将军坟进行稳定性评价和采取有效的防护对策有重要意义。更多还原

【Abstract】 Based on the field investigation and the engineering geological exploration,the deformation failure characteristics of Jiangjunfen was analyzed. The changes of the stress field and the rules of the deformation failure of Jiangjunfen under three cases,the gravity field and the local soft foundation and the ground water seepage field,were researched respectively using FLAC technique. The simulation results show that the deformation failure mechanism of Jiangjunfen is a gradual developing process. Firstly,the whole structure of Jiangjunfen subsided into the local soft foundation,then leading to the decline of the northern part of the structure,accompanying with the tensile fracture among stones and the heaving of the groundsill,and at last resulting in the stones sliding and the large scale structure deformation failure of Jiangjunfen. It is helpful to evaluate the stability of Jiangjunfen and to adopt preventing measures to control the evolutional deformation of Jiangjunfen with the research conclusion.更多还原
