按照近五年莫斯科总体发展计划,需要修建45km的地下铁道,预计到2000年将有50～55km的线路投入运行.为了保证高度高低成本地修建地下工程线路,必须可靠地掌握工程开发区的工程地质情况. 地质剖面由白垩纪和第四纪沉积组成.白垩纪有水平沉积的亚普第阶砂层(K_1ap)阿尔必组泥质砂层(K_1al),后者层厚从6m变化到39m、平均约20m.上白垩纪分布的
According to the overall development plan of Moscow in the recent five years, a 45km underground railway needs to be constructed and it is estimated that 50 to 55km of lines will be put into operation by the year 2000. In order to ensure the construction of underground engineering lines at a high level and low cost, it is necessary to master the engineering geology The geological profile is composed of Cretaceous and Quaternary sediments, Cretaceous alluvial-subsoil (K_1ap) albite sands (K_1a1), which change from 6m to 39m in thickness, Average about 20m. Upper Cretaceous distribution
