Restoration Design and Calculation of Shaft Joint in Complex Stratum

Abstract:

Article Preview

On account of the fracture status of shaft joint in complex stratum, we analyze the reasons causing damage, then put forward restoration plans, such as, controlling water and consolidate the weak stratum by grouting, and strengthen the shaft supporting. We also propose to enhance supporting shaft thickness reasonably through shaft calculation, checking, and numerical simulation. In addition, bolting support with metal mesh and cable system should be adopted in the combined support of weak surrounding rock, double bolt plates should be used to enhance the links between shaft and surrounding rock, and the support effect should also be monitored.
