山体崩塌是山区常见的不良物理地质现象,由于它们所处特殊的地形,地质条件,山体崩塌都是突发性的,危害性大。崩塌常给交通、城镇、人们生命财产、国民经济建设带来巨大威胁和经济损失。武隆县乌江鸡冠岭岩崩产生,不仅与地形、地质条件有关,而且与无序的人类工程活动有很大的关系。乌江鸡冠岭岩崩规模巨大、危害性大,破坏了新建的武隆煤矿、阻断乌江航运、摧毁轮船,造成较大的人身伤亡。所以,研究乌江鸡冠岭岩崩成因,提出科学的防治对策,防止类似崩塌产生给人们生命财产、国民经济建设带来危害,具有重大的现实意义。
Mountain collapse is a common adverse physical geology phenomenon in mountainous areas. Because of their special terrain, geological conditions and mountain collapse, all of them are sudden and harmful. Collapse often brings great threats and economic losses to transportation, cities and towns, people’s lives and property, and national economic construction. The rock fall of Jiguanling, Wujiang County, Wulong County is not only related to the topography and geological conditions, but also to the disordered human engineering activities. The Wujiang Jiguanling rock avalanche scale is huge and harmful, destroying the newly built Wulong coal mine, blocking the shipping in the Wujiang River, destroying the ships and causing great casualties. Therefore, it is of great practical significance to study the causes of the rock fall in Jiguanshan Ridge, Wujiang, propose scientific prevention and control measures, prevent similar landslides from giving birth to people’s lives and property, and jeopardize the national economic construction.
