    摘要:

    皎平渡山洞遗址位于金沙江河谷左岸,属于不可移动的石质文物。该崩坡积土是在后期钙质溶滤、沉淀和成岩作用下,形成的次表生岩类,强度具有离散性。本文在查明山洞遗址斜坡地质条件基础上,采用基于可靠度理论对遗址斜坡在水库蓄水、降雨和地震工况条件下的稳定性进行了定量评价和稳定性分级。

    Abstract:

    Jiaopingdu cave site located on the left bank of Jinsha river valley, is an immovable stone relic. The slope collapse soil is a kind of sub-surface rocks formed by calcareous leaching, precipitation and diagenesis, and its strength is discrete. In this paper, based on the geological conditions of the slope of the cave site, the stability of the slope under the conditions of reservoir storage, rainfall and earthquake is quantitatively evaluated and graded by using the reliability theory.
