Abstract:
The paper presents the general situation as well as the engineering conditions of the first-period project of the North-South line of Nanjing metro .The topographty is complicated along the metro construction line .It has to cross bedrocks flood basin, the saturated silt and fine sand in ancient riverbeds .And engineering geological problems will be caused:regional stability , sand liquefaction , the stability of surrounding rockmass or soilmass , water inflow and seepage deformation, ground differential subsidences.Using preferred plane theory , these problems are discussed and the countermeasures are given.It has been proved by practices that it is vitally important for the reconnaissance and constructional plan to recognize the engineering geological problems clear and make scientific evaluations.
