A study on the soft soil’s property in the area of Nantong-Haimen expressway

The soft soil's property of the area where the expressway is passed in Nantong-Haimen is analyzed in particular.At the same time,the regression equation between the physical index and the mechanical index is establ ished by the geomathematics method.At last,according to engineering practice,the soft's allowable bearing capacity is put forward.
