近海平原-丘陵区地铁路基设计方法

Design Method of Subway Subgrade in Coastal Plain Hilly Area

我国广东、浙江、福建等地区存在大片的近海平原-丘陵区,此区域的地质条件由岩石向海相沉积急剧变化。在此类地质条件下建设城市地铁的地面路基存在着诸多困难,且尚未有成熟、系统的路基设计方法。通过参考、类比、数值模拟等方法,研究了近海平原-丘陵区路基工程的设计难点,系统性地形成了近海平原-丘陵区路基设计方法。

There are large coastal plain hilly areas in Guangdong, Zhejiang, Fujian and other areas of China. The geological conditions in this kind of area change sharply from rock to marine sedimentation. Under such geological conditions, there are many difficulties in building subgrade project of subway, and there are lacking of mature and systematic subgrade design method. Through reference, analogy, numerical simulation and other research methods, in this paper, the design difficulties of Subgrade project in coastal plain hilly area have been studied, and the subgrade design method in coastal plain hilly area has been systematically formed.
