Abstract: Firstly, this paper introduces the common geological disasters, such as landslide, debris flow, land subsidence and so on. Then it summarizes the application strategies of hydraulic environmental geological technology in geological disaster treatment, such as geological radar technology, transient electromagnetic method, remote sensing technology, three-dimensional laser scanning technology and GPS-RTK technology. Finally, combined with the working experience, some suggestions are put forward to ensure the smooth development of hydraulic environmental geological survey, such as doing a good job in the survey of engineering geological environment and paying attention to the construction of hydraulic environmental geological survey team, which provides a certain reference for improving the effectiveness of geological disaster prevention and treatment.
Key Words: Hydraulic environment geology; Transient electromagnetic method; Geological hazards; 3D laser scanning
水工环地质调查是对水文地质、工程地质、环境地质进行调查作业的统称。在野外工程建设中,各类地质灾害不仅直接影响工程质量,而且也會对正在施工作业的人员构成安全威胁。为了了解地质灾害的类型,制定行之有效的防治措施,必须要借助于水工环地质调查技术,对工程所在地区的地层岩性、岩体天然应力状态、水文地质条件、周边环境等展开全面调查,在收集相关资料的基础上采取措施,降低地质灾害的发生率,控制地质灾害的危害后果。
1 常见地质灾害类型
1.1危岩和崩塌
危岩是指山坡上松动、开裂,随时可能掉落的岩石。岩块、土体在重力作用、风化作用、振动作用的影响下,突然掉落沿着坡面向下滚动的现象,即为崩塌。根据崩塌体的不同,如果以土质为主,则为土崩;如果以岩石为主,则为岩崩。崩塌多发生于倾斜度在60°以上的坡体上。
1.2滑坡与泥石流
滑坡与泥石流是山区比较常见的地质灾害类型。……
