Soft rock project with large deformation has the characteristic of large stress releasing in excavate and will appear large deformation in the project construction process.If we choose the traditional rock blot support, the rockmass large deformation is able to snap the rock blot.In this paper, we shall briefly introduce the new-typed yield bolt for soft rock project with large deformation.This new-typed yield bolt was a pressure dispersion-type yield bolt, and has the yield supporting device at the bottom of the rock bolt.Three are three stages for supporting mechanism analysis of yield bolt.The yield bolt not only disperse the stress of anchoring body, but also appear yield deformation.It is could be applied to soft rock project with large deformation.
