Abstract: According to the principle of effective stress,the general model for lateral resistance on the shaft wall has been constituted in this paper.The lateral resistance results from soil consolidation settlement at the bottom of overburden around the shaft.On this shaft wall,there is not only negative,but also position and zero skin friction.The distribution of lateral resistances determines the position where compressive fracture and tensile strain occurred.Moreover,the relationship between the shat fracture and rainy season has been illustrated on the basis of the variety of the effective stress.
