The effect of surface soils subsidence on the strength of shaft wall and research of the prevention measures
JING Lai-sheng
Abstract：Through the analysis of the reason about surface soil subsidence , the danger position of the shaft wall fracture is located .The reverse frictional force that results in the failure of the shaft wall is analyzed , the analytical equation for calculating the stress in the danger position is obtained and the strength criterion of shaft wall is set up ，and through the concrete of the fracture reasons about shaft wall of the four shafts in Baodian Mine the rightness and applicability of the theory is proved .Finally based on the stress state of the danger point and the strength criterion of shaft wall, the measures used to prevent the fracture of shaft is advanced. It has more great guidance significance to construction field and engineering design .
