枣庄市市中区岩溶地面塌陷预测评价

岩溶塌陷是枣庄市内的重要地质灾害.以枣庄市市中区为例,借鉴区域地质灾害评价预警时空递进分析理论体系和整体思路,结合研究区实际情况,采用有实际研究意义的评价指标,尝试在岩溶塌陷地质灾害密集发生的小区域内开展预测评价工作,在研究区建立了岩溶塌陷地质灾害“发育度”、“潜势度”、“危险度”、“危害度”四级评价体系.并进行了四度区划与分区,其中“发育度”、“潜势度”、“危险度”划分为四级,“危害度”划分为五级,对岩溶发育进行了预测评价.

Predication and Evaluation of Karst Collapse in Shizhong District of Zaozhuang City

Karst collapse is a kind of important geologic hazard in Shizhong district of Zaozhuang city. Setting Shizhong district of Zaozhuang city as an example, referring the theory and integral thought of regional geological hazards evaluation and early warning analysis, combining with practical situation of research areas, by using evaluation factors which have practical meaning, predication and evaluation have been carried out in geological hazards concentration areas. Four-degree evaluation system of karst collapse disasters has been set up in study area, they are "developing degree", "potential degree", "dangerous degree" and "harmful degree". Among them, "developing degree", "potential degree", "dangerous degree" can be divided into four degrees, and "harmful degree" can be divided into five degrees, and development degree of karst has been predicated and evaluated.
