需要修建一个由三条干线所组成的地铁网络──一条区域线和两条市内线──这是在１９７０年到１９７４年间对大开罗市所进行的交通研究得出的结论。一条长４．５ｋｍ的地铁线在市中心商业区（Ｃ．Ｂ．Ｄ）施工，以便分别与两条既有的东北东南走向、沿Ｃ．Ｂ．Ｄ南北边沿的铁路线相连。对这些线进行了现代化改造，用以构成４２．５ｋｍ的一号线（区域线）。１９８７年９月２７日，第一阶段（２８ｋｍ）区域线开通，成为非洲和中东地区的第一条地铁线。第二阶段完成４２．５ｋｍ区域线，于１９８９年４月开通。网络中的第二条线（二号线─—市内线）目前正在施工。现在已开始地面和高架部分以及地面上多层楼车站的施工。隧道的明挖部分和地下车站（本线的第一阶段）的施工预计在９２年中期前开始。本文论述了网络中第二条线的施工，该线通过了高地下水位区和构造复杂的冲积土地区。说明了修建通过本市最拥挤、人口最稠密部分线路预计采用的施工方法。本线的施工计划分两个阶段，本文详细说明了第一阶段的施工方法和设计标准。
The need to build a metro network of three main lines - a regional line and two city lines - is the conclusion of a traffic study of the city of Cairo from 1970 to 1974. A 4.5km metro line is being constructed in the downtown business district (C.B.D.) so as to be respectively contiguous with two existing northeast southeast directions. B. D north-south edge of the railway line connected. The lines were modernized to form Line 42.5km (Regional Line). September 27, 1987, the first phase (28km) regional line opened to become the first subway line in Africa and the Middle East. The second phase completed 42.5km regional line, opened in April 1989. The second line in the network (Line 2 - Metro) is currently under construction. Construction of floors and elevated sections and multi-story stations on the ground have now begun. Construction of the open cut section of the tunnel and the underground station (first phase of the main line) is expected to start before mid-1992. This article discusses the construction of the second line in the network, which passes the high groundwater level area and the complex alluvial soil area. Described the construction of the city through the most crowded, the most densely populated part of the line is expected to use the construction method. This line of construction planning is divided into two phases, this article details the first phase of the construction methods and design standards.
