【Abstract】 The geological situations of shadow layers in Shanghai area have been analyzed. Based on that and according to the time of the land formation, as well as the distribution characteristics of muddy soils and sandy soils, the classification of dangers to the construction of underground engineering projects caused by geological conditions has been studied by zonal approach.更多还原
