摘　　要：本文通过地质类比法,分析了塔基所在老滑坡特征及其成因,通过定性分析和定量计算的方法,评价了滑坡稳定性,在此基础上,结合塔基周围地质环境发育特点,对位于斜坡浅表部塔基地基的稳定性进行了分析,评判了塔基立塔的适宜性,结果表明:塔基所在的斜坡为岩质滑坡堆积形成的厚层堆积体,滑坡堆积体处于稳定状态,除10L337塔基浅基础存在安全隐患外,其余塔基稳定性较好,适宜立塔。In this paper,the causes of the landslide where the tower located foundations were analyzed by the geological analogy method. The stability of the landslide foundations was evaluated by qualitative analysis and quantitative calculation. Based on the characteristics of the geological environment around the tower foundations,the stability of the foundation of the superficial parts of the slope was analyzed,and the suitability of the tower foundations was evaluated. The results show that the slope where the tower was located was a thick layer accumulation body formed by rocky landslide,and the landslide accumulation was in stable state,besides the 10 L337 tower shallow foundation was potentially unsafe. The stability of other tower foundations was relatively good and suitable for tower construction.
