| 摘 要： | 应用ANSYS软件建立边坡岩体有限元模型,根据边坡变形观测资料,反演确定边坡弹性变形参数和蠕变参数。根据边坡岩体内顺坡向节理较为发育的情况,考虑利用正交各向异性材料特性进行模拟,并与各向同性材料的成果进行对比,深入研究边坡蠕变变形的规律和影响边坡变形的主要因素,指出了边坡变形的成因和未来的变形趋势。 |

| Abstract: | The FEM model of the slope with ANSYS is established and the back-calculation of the parameters of elastic deformation and the creep are carried out on the basis of the field data.According to the cleavage in the direction of slope is developmental,it is simulated with the orthotropic material characteristics and compared with the production of isotropic material.Besides the law of the creep deformation and the main influenced factors are deeply strudied.Last,the causes of the slope deformation and the trend of the deformantion are pointed out. |
| Keywords: | rock slope creep orthotropic deformation back-calculation |
