摘　　要：通过对西南地区红层边坡的实地调查研究,并结合前人的研究资料,对红层边坡岩体结构和破坏形式进行统计分析。分析表明:红层边坡岩体结构归纳总结为层状结构、碎裂结构、散体结构和基覆二元结构四大类,层状结构进一步细分为五个亚类;红层边坡破坏形式划分为顺层滑动破坏、软弱互层破坏、楔形体破坏、倾倒破坏、风化剥落和坡面冲蚀六类;针对红层特性,对红层边坡的加固防护提出了放缓边坡、分格排水、植被保墒工程措施,实践工程防护和生态防护有机结合的理念。The statistical analysis of the red-bed slope rock-mass structure and its destructional form based on field investigation and the research of red-bed slope in the southwest of China with the combination of formers'studies is carried out.The structures of red-bed slope rock mass were generalized to four categories,including stratified structure,fracture structure,loose structure and bedrock-clad binary structure,in which the stratified structure was ulteriorly fractionized to five subgroups.Meanwhile,the destructional forms of red-bed slope were generalized to six categories including bedding slip failure,weak inter layer failure,wedge failure,topping failure,weathering flake and slope surface erosion.Finally,in allusion to the characteristics of red-bed slope and its reinforcement and protection,we put forward the concept which achieved the organic combination of engineering protection and ecological environment via decreasing the slope,drainage compartmentally and the maintenance of soil moisture conservation.
