云南干线公路边坡灾害形成分类及机理

Formation Classification and Mechanism of Yunnan Main Highway Slope Disaster

对于地形和地质条件复杂的地区,边坡的存在往往会导致或潜藏一些地质灾害。本文结合云南山区干线公路的修建,对云南山区干线公路产生的地质灾害进行细详调查、分析,将其分为了坍塌、滑坡、崩塌和错落四种病害;根据云南区域地质情况,从地层岩性、地质构造、天气情况和地震影响等方面,研究了各类病害的形成机理;对各种病害,提出了具体的治理措施,特别针对地下水的影响,提出了有效的防治措施,大大减小了发生灾害的可能性。从而为此类山区道路工程的施工和治理提供了可参考的经验,具有重要的应用价值。

For areas with complex terrain and geological conditions,the presence of slopes often leads to or hides some geological hazards.Based on the construction of the main road in the mountainous area of Yunnan,this paper conducts a detailed investigation and analysis of the geological hazards generated by the main road in the mountainous area of Yunnan,and divides it into four kinds of diseases:collapse,landslide,slide and staggering.According to the regional geological conditions in Yunnan,the formation mechanism of various diseases has been studied from the aspects of stratigraphic lithology,geological structure,weather conditions and earthquake impact.For various diseases,specific control measures are proposed,especially for the impact of groundwater,effective control measures are proposed,which greatly reduces the possibility of disasters.Therefore,it can provide reference experience for the construction and management of such mountain road projects,and has important application value.
