摘    要:通过对云南省内红层岩土工程特性的初步研究以及在红层地区的工程建设实践,分析和介绍了红层岩土体的物理力学特性、红层边坡变形破坏过程—蠕变、剪切、滑移 3 个阶段的特点及红层滑坡呈周期性扩展的机制特征,并结合工程实例,论述了红层边坡变形破坏对工程建设的主要危害—滑坡危害和蠕变危害。根据红层边坡变形破坏特点及工程的性质和安全要求,提出了对红层边坡危害的防治对策。

关 键 词:红层  岩土工程特性  边坡变形破坏机制  危害防治

Abstract:Through studying characters of geotechnical engineering of red strata and engineering practices in the red stratum area of Yunnan province, the physico-mechanical characters of the red strata, the distortion-destruction process of slopes of red strata, which are the three stages—the creep, the shearing and the slide, is analyzed. It also analyzes and introduces characters of mechanism of cyclic enlarging of landslide of red strata; and discusses the main hazard of distortion destruction of slopes of red strata, which is the landslide hazard and the hazard of creep, with engineering example. The controlling countermeasures for the hazard of slopes of red strata are suggested accoding to the distortion-destruction characters of slopes, the character and safety of buildings.
Keywords:red stratum  character of geotechnical engineering  distortion-destruction mechanism of slope  hazard contro1
