摘　　要：本项研究是在以往的勘察资料的基础上进行的。通过现场调研、凯塞尔效应测试、ESR测试和数值模拟,然后进行1:400的大比例尺相似材料地质力学模拟。上述系列研究成果表明,黄腊石滑坡的深部破裂带是在先期结构面的基础上,经过斜坡应力应变场的改造和发展而形成的,具有明显的时间效应,各破裂带最终可能互相贯通。因此,建议治理方案拟针对深部变形为宜。This geomedhanical modelling research using similar materials with scale 1 : 400 was conduct ed based on the geological survey data provided by the ' Headguarters' , field investition, Kaiser of feet test. ESR test and numerical simulation. The results indicated that the deep fracture zones in Huangtashi landslide were produced due to the changes and development of stress - strain field in slope on the bases of the previous structure surfaces. They were obviously time dependent and might be linked with each others finally. Consequently the suggested treatment plot be better focused on the deep deformation.
