| 摘 要： | 以渭河中游陕西省宝鸡市李家窑滑坡为实例,在搜集大量资料的基础上,运用先进的软件给出了重建滑前地貌所必需的3个要素,即现今实际地貌形态、滑床面形态和滑动后的地貌形态,并进行了滑前地貌重建.依据重建的结果,得到了滑坡发生前的许多重要参数,如滑坡的稳定性、重量、体积、初滑角以及质心的滑动角度和释放的势能等.最后对该滑坡从滑前到现今各阶段的滑坡稳定性演化进行了分析.

| Abstract: | In this paper,as a living example the topography reconstruction for Lijiayao Landslide in Baoji City, Shaanxi Province, which lies in the middle reaches of the Weihe River was explained.Three indispensable conditions for the pre-failure topography reconstruction, i.e. present topography, basal sliding plane morphology and post-failure topography was presented. Bosed on the result of reconstruction, many important parameters such as stability, weight, volume, initial sliding angle, mean sliding angle of the mass center and potential energy release were obtained. Finally, the landslide stability evolution from the pre-failure to the present status was analyzed. |
