Research on Nanning No.1 Subway Strata Combination Model and Regionalization

Analyzing and summing up the engineering geological and hydrogeological features of Nanning No.1 6 Subway, types strata combination model are put forward, which combing the first exploration data. Then the URT Line 1 is divided into 5 kinds engineering geology partition. At the same time, all engineering geology partitions engineering characteristic and engineering problem possibly appears are analyzed, drawing a conclusion that these first three types partitions shield tunnel may have more problem in the process of construction.
