METHODS FOR BEARING CAPACITY DETERMINATION OF TYPICAL SOIL FOUNDATIONS IN NINGBO REGION

This paper is based on the first-stage in-situ test results of the Line 1 and Line 2 in Ningbo rail transit system.The tests include static cone penetration,standard penetration test,standard penetration test,and vane shear test.Accordingly,the foundation bearing capacities of the typical soils in Ningbo region are estimated and predicted with empirical formula.Then,the distributions and numerical characteristics of the predicted results are presented on basis of the K-S inspection method.Based on above analysis results,the recommended foundation bearing capacities of the typical soils are proposed after their comparisons with the empirical foundation bearing capacities of the typical soils in Ningbo area.The research findings can provide scientific references to determine the value of the bearing capacity of the geotechnical investigation and design in Ningbo area.
