摘要
济南市地处华北平原地面沉降区的东南边缘,地面沉降调查与防治工作起步相对较晚,2011年5月19日济南市政府令第243号发布了济南市地质灾害防治管理办法,将地面沉降纳入济南市重点防治的地质灾害之一,有力推进了地面沉降灾害防治工作。2017年7月济南市批复了《济南市地面沉降防治规划(2016—2025)》《规划》明确了济南市地面沉降防控目标、任务,对地面沉降防控工程进行了部署。目前,济南市已完成北部平原区的地面沉降调查与评价工作,建立了基岩起算点、GPS监测墩、GPS监测点、监测标石、二等水准测量线路、分层标、地下水监测孔为基础的地面沉降监测网络,取得了地面沉降监测基础数据,填补了济南市地面沉降工作的空白,为今后济南市地面沉降监测预警体系的建设奠定了基础。
