山东省枣庄市市中区地质灾害调查与防治

Survey and Prevention of Geological Hazards in Middle District of Zaozhuang City

摘要:

枣庄市市中区主要地质灾害有喀斯特塌陷、采空塌陷和崩塌。地质灾害易发区划分利用袭扰系数法,按易发程度依次为高易发区、中易发区、低易发区及不发育区。地质灾害点按规模、危害和潜在危险性划分为危险性大、危险性中等、危险性小3级。在评估基础上确定了地质灾害重点防治区、次重点防治区、一般防治区。对喀斯特塌陷应通过地下水的合理开发利用结合工程治理予以防治;对山体崩塌应以避让为主;采空塌陷应侧重土地综合开发治理。

Abstract:

Major hazards in middle district of Zaozhuang city are karst collapse, stope out collapse and break down. Using disturbing ratio method and according to easy-happening degree, geological hazards easy-happening areas can be divided into high easy-happening area, medium easy-happening area, low easy-happening area and not happening area. According to scale, damage and potential dangerous degree, geological hazard spots can be divided into high dangerous degree, medium dangerous degree and low dangerous degree. On evaluation basis, major prevention area, second-emphasis prevention area, and general prevention area are classified. Combining reasonable exploration and utilization of underground water with engineering management, karst collapse is prevented; hill break down should be avoided majorly; and stope out collapse should be tuilized and managed comprehensively.
