Abstract
According to the geological topographic characteristics of K0 + 400 ～ K1 + 498 high loess slope in South Slope-Ci'en Temple section of Lanzhou, Gansu Province, the finite element software is used to simulate the slope support and unsupported working condition. The deformation of the slope, the distribution of the plastic zone and the stability of the slope are compared and analyzed under two working conditions. Analysis shows: the trend of horizontal displacement increment of the points at all levels of unsupported excavation and timely supported excavation is basically the same and the horizontal displacement is pointing to the outside of slope, the horizontal displacement in the middle of the slope is the largest and the horizontal displacement in the top of the slope is the smallest. In the vertical deformation, the high measurement point shows a larger deformation than the low measurement point under the support and unsupported conditions, the largest vertical deformation occurs in the top of the slope, unloading rebound appears in each level of excavation. It can be shown that the support measures can effectively reduce the horizontal and vertical deformation so as to maintain the slope stability.关键词
