摘要
地面沉降是北京平原区最主要的地质灾害之一。本文从北京地区地质构造和第四纪地层沉积特点入手,分析平原区可压缩地层的特征与分布范围,寻找地面沉降与地质结构间的关系;并从第四系地质特征出发,合理选择地面沉降分层监测层位,系统地提出了适宜北京地区的地面沉降分层监测方法。
Land subsidence is one of the most serious geological hazards in Beijing plain. Special geological conditions are the basis of land subsidence development. Based on the geological structure and Quaternary characteristics in Beijing plain area, this paper analyzed the characteristics and distribution of compressible stratum, and tried to ifnd the relationship between land subsidence and geological structure. Then, the paper described how to make a reasonable arrangement of layered boreholes for land subsidence according to the Quaternary geological features, and proposed a layered monitoring method suitable for Beijing area.
