滑坡是山区地区发生比较频繁的自然灾害。滑坡一旦发生,无论其规模大小,滑动速度快慢,均会对地面、农田、植被等造成破坏。规模巨大或滑动剧烈的滑坡,堵截河道,中断通航,严重摧毁公路、铁路、桥梁、房屋等工程建筑设施,造成极大的经济损失。笔者涉足都江堰市两河乡山区,进行地质土质和山地资源调查时,对该乡盐井村一组山体滑坡(下称盐井村滑坡)进行了实地调查。并在查明滑坡产生原因、危害性基础上,提出了切合实际的整治滑坡的措施。
Landslides are frequent natural disasters in mountainous areas. Once a landslide occurs, no matter the size or the sliding speed, it will damage the ground, farmland and vegetation. Large-scale or sliding landslides, interdiction of rivers, interruption of navigation, and serious destruction of highways, railways, bridges, houses and other engineering and construction facilities, causing great economic losses. When I was involved in the investigation of the geological soil and mountainous resources in Duhehe Township, Dujiangyan City, I conducted a field survey on a group of landslides in Yanjing Village of the township (hereinafter referred to as Yanjing Village landslide). On the basis of ascertaining the causes and hazards of the landslide, this paper puts forward some practical measures to control landslides.
