摘要

通过对1920年海原大地震造成的石碑塬滑坡区域地质条件和基本特征的现场调查,推测出石碑塬滑坡的边界、形成原因及破坏过程,并通过数值模拟分析其原始斜坡在地震作用时的位移、应变等特征。
In this paper,an on-site investigation on the geological conditions and basic characteristics to Shibeiyuan landslide area impacted by Haiyuan earthquake in 1920 has been made.We infer the boundary,formation causes,and failure process of Shibeiyuan landslide,and analyze its original slope displacement,strain and other characteristics by the action of earthquake through numerical simulation.
