万县市是长江上游港口城市。城区很大一部分座落在六大滑坡群上。近年来,局部出现复活现象。据调查统计,城区现共有滑坡、危岩47处,体积23370.42×10~4m~3。无时不在威胁着万县市。1994年底,由国家科委下达任务和受万县市委托,我们进行了万县市地质灾害风险评价研究。 Wanxian City is the upper reaches of the Yangtze River port city. A large part of the city is located in the six landslide group. In recent years, there has been a partial resurgence of phenomena. According to the investigation and statistics, there are 47 landslides and dangerous rocks in the urban area with the volume of 23370.42 × 10 ~ 4m ~ 3. Wanxian always threatens the city. By the end of 1994, commissioned by the State Science and Technology Commission and commissioned by the Wanxian City, we conducted a Wanxian Geological Disaster Risk Assessment Study.
