岩石力学性能为工程地质界所重视 ,但却甚少关注糜棱岩 (特别是超糜棱岩 )的工程地质意义。测算了郯庐断裂带南段的糜棱岩类的抗压、抗剪强度的系列参数 ,从而发现超糜棱岩的抗压强度可高达 2 4 0 .3 MPa,其内聚力可高达 65.5MPa,并与其他岩石的抗破性能进行比较分析 ,进而探讨了韧性剪切带糜棱岩的工程地质意义 Rock mechanical properties are valued by engineering geology, but little attention has been paid to the engineering geological significance of mylonites, especially supermylonites. The series of parameters of mylonite compressive strength and shear strength in the southern section of Tanlu fault zone were calculated. It was found that the compressive strength of the super mylonite can be as high as 240.3 MPa, the cohesive force can reach as high as 65.5 MPa, And compared with other anti-breaking performance of rocks, and then explored the ductile shear zone mylonite engineering geological significance
