| 摘 要： | 甘肃省天水市麦积区三岔乡不稳定斜坡、崩塌、泥石流等地质灾害十分发育,灾情、险情严重。本文拟以甘肃省天水市麦积区三岔乡为例,研讨地质灾害在不同工况条件下的稳定状态及形成机制,确定地质灾害的发生概率,评价地质灾害危险性,并预测地质灾害威胁范围。结合地质灾害易发程度分区评价,进行地质灾害危险性分区评价、工程建设适宜区划分,并提出科学有效的地质灾害防治对策。

| Abstract: | Taking Sanchaxiang Town as an example, this paper attempt to discuss the issue about assessment and prevention of geological hazards in township. The authors summarized the features of geological hazards including unstable slope, collapsing and debris flow, analyzed steady situation and forming mechanism,determined probability of geological hazards. Based on evaluation of hazard susceptibility, the area perhaps affected from geological hazards were predicted. Finally, the prevention and control countermeasures are put forward. |
