A Study on the Impact of Structure Plane on Unloading Rock Mass Deformation

Abstract:

The rock mass deformation properties of unloading is very different from loading.The physical and mechanical properties of structural plane can bring a very great influence to rock’s unloading behavior. The lower the strength parameter of joint plane and the greater the angle of joint, the lower the unloading modulus of deformation. The greater the connectivity of joint,the faster the unloading modulus of deformation descend. In any case unloading amount is near linear relation with descend amount of unloading deformation modulus.
