北京城建工程基坑和地面塌陷灾害研究

Engineering Foundation and Ground Collapse in Beijing Urban Construction

城市人类工程活动等已经成为强大的地质营力,强烈地参与到自然地质作用之中。北京城市建设工程基坑和地面塌陷是城市引发的新的地质灾害,目前尚未进行地质勘查和研究,其危害性也处于未知状态。开展城市地面塌陷灾害勘查和风险评价,是提高城市地质安全保障能力迫在眉睫的城市地质工作之一,也是地质工作服务于城市管理的重要内容,对于北京这样的国家首都城市健康发展具有相当深远的意义。

Artificial engineering activities in cities have become a forceful geologic agent, which participates intensively in the natural geologic processes. The engineering foundation and ground collapse in Beijing urban construction is a new geologic hazard incurring in the city, which has not been explored and studied, and so its harmfulness is still unknown. To carry out exploration of the ground collapse in the city and its risk evaluation is one of the geologic work urgently needed to enhance the guarantee ability of the city for geologic safety, and is also an important content of geologic work serving the urban management, which has a profound significance for the healthy development of metropolises like Beijing.
