摘要

通过调查研究朝阳坡平缓泥质粉砂岩滑坡，对其滑坡产生的地质条件、软弱夹层与斜坡和冲沟的关系、软弱夹层的强度指标、裂缝的发展等进行了分析。根据对红砂岩滑坡规律的认识，及时在滑坡发展阶段撤离该地区居民，避免了生命财产的重大损失。平缓红砂岩滑坡的内在因素是软弱夹层及其临空，外在因素是强降雨使其抗剪强度降低。通过实例加深了对滑坡机制的认识，为从事类似滑坡调查和相关工程的科研设计、施工、监理人员提供了参考。

Abstract

Chaoyang slope is a typical landslide

which is composed of gentle inclined argillaceous sandstone. By investigation of the slope

its engineering geologic conditions

buried weak layers

gullies’ relationships

strength parameters and the development of fractures are acquired and analyzed. Based on the knowledge of landslides of red sandstones

residents on it can remove to safety place before the onset of the landslide; and then heavy accident can be avoided. The intrinsic factors of red sandstones’ landslides are buried weak layers and the formation of their free faces; and the external course is the decrease of shear strength due to the heavy rainfalls. Chaoyang slope is a good example of landslides; and its analyses should be useful for any workers related to landslides.
