Mechanicai Analysis of Rock Mass with the "Plate Fracture" Structure

On the basis of the new concept of the "plate fracture" structure Presented by Sun Guangzhong et al., this paper discusses the grounds for differentiating in from the stratified structure, and the differences of their mechanical models used. The engineering practice showes that in stability analysis of underground cavities, slopes and dam foundations the characteristic method of the "plate fracture" structure sometimes leads to better ecomie effects.
