摘要
Based on summarizing the codes about division standards of layered rock mass structure,the differences and shortages of discontinuity spacing as the rule are pointed out,and the new cognizance for the scheme of layered rock mass structure is taken forward.The huge thick layered structure is divided into two sub-classes further,which are >1 m and >2 m,and the interbed structure is included in other layered structures as a whole.The interlayer structure with more pertinence is put forward,as for the characters of weathering and unloading and shear zone of layered rock mass.At last,the division schemes of close to horizontal layered rock mass structure,which are applied to Guxian Project,are founded preliminarily,combined with the statistical data of average and percentage of discontinuity spacing of some rock groups where the buildings are involved.
