OPTIMMIZATION OF SUPPORTING PARAMETERS ON SHOTCRETE AND BOLTLINING
喷锚支护参数的优化确定

The paper follows the NATM prinsiple to transfer fully the ability of surrounding rock in self support so that the deformation pressure is minimum on the supporting lining.Through the medium ofestablishing the relation between supporting diceplacement and structure stiffness,by means ofoptimization method,to adjust continuously structure stiffness,the paper finally gives reasonable supporting parameters.
