秦皇岛市地质灾害风险区划的思考与探索

Reflections and Exploration on Geological Zoning of Qinhuangdao

秦皇岛市已发现崩塌、泥石流、滑坡、采空塌陷等各类地质灾害点204处,已发生地质灾害111处,占54%。其中,人类工程经济活动与地质灾害形成发展关系密切。保护地质环境与生态环境,可采取加强地灾防治宣传,制止无序群采,禁止山区放牧,科学合理开采地下水,防止海水入侵,在群测群防的基础上,采取必要的工程治理措施。

It is found that there are 204 spots vulnerable to geological hazards in Qinhuangdao city,including cave-in,debris flow,landslide,and collapse of mined-out areas.111 of these geological hazards have happened,amounting to 54%.The forming and development of these disasters are closely related to the economic and engineering activities of human beings.The protection of geological and ecological environment could take the measures of trengthening the disaster prevention and control propaganda and stopping the disorder mine massively,and banning grazing of mountains,and rational exploitation of groundwater,and preventing seawater invasion,making necessary treatments for the projects based on the mass prediction and disaster prevention.
