Abstract: Combined abrasion and mechanical strength experiments of tunnel rock mass with TBM construction technology,abrasion values and mechanical strength values of rock are obtained. The correlative model between abrasion and mechanical strength is builted by regression analysis method. The research results indicate that the compressive strength,tensile strength,cohesion and point load strength are in exponential relationship with abrasion of rock,and the internal friction angle of rock is in logarithm...
