DISTRIBUTION LAW AND HAZARD MITIGATION STRATEGIES OF LANDLIIDES IN QINGJING RIVER VALLEY, HUBEI
摘要
Abstract
The Qingjiang River Valley is the high susceptible area of landslide in Hubei Province, where the landslides have caused a great deal of economic loss and have great threats to local people. The geological environment of the studying area is complicated. There are deep rivercut valleys and steep bank slopes. The geological structure is developed. There were large-scale intermittent ascending motions in the aspect of neotectonic movement. There are 2843 landslide hazards in the studying area. They include 2275 landslides and 568 collapse-landslides. .Most of the landslides are small-scale and are mainly distributed at the region with frequent human activities. According to the statistics analysis, the space distribution law of the landslides in the Qingjiang River Valley depends on the geological environmental and dynamic factors. The dynamic factors include natural dynamic factors and human dynamic factors. The former is mainly the rainfall. The later is the increasing cutting slope work by human activities. The time law of the landslides is synchronous, hysteresis and unstable period. The self-action law of landslides is inheritance , concealment, burstiness and diversity. Based on the investigation on the geological environmental conditions and the basic characteristics of the landslides in the studying area, the mitigation strategies for landslide hazards in the studying area are are proposed correspondingly. They include monitoring and early warning, relocation and movement, engineering improvement, and geological environment protection.关键词
