天津突发性地质灾害发育特征与形成条件

摘要

通过对已知地质灾害点的统计分析,总结归纳天津市北部山区突发性地质灾害的发育特征和分布规律,分析研究突发性地质灾害与地形地貌、地层岩性、地质构造、降雨和人类工程活动等形成条件的关系,为政府部门防灾减灾提供科学决策依据,更好地为本市公共安全工作服务.%Based on statistical analysis of known geological hazard points,this paper summarized the development characteristics and laws of abrupt geological hazards in northern mountainous area of Tianjin.The relationships between abrupt geological hazards and topography and geomorphology,formation lithology,geological structure,rainfall,human engineering activity,etc,were studied.The results could provide the scientific basis for disaster prevention and mitigation for government departments and city's public safety services.
