摘要
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 。
The mechanical properties of rocks are very significant to the engineering geology and have been paid great attention to. However, the significance of those of mylonites(especially the ultramylonites)to engineering is seldom paid attentions to by the former reserchers. The compressive and shearing strengthes of the mylonites from the southern part of Tancheng Lujiang fault belt are determined and it is found that the compressive strength and cohesive force in ultramylonites can reach 240.3 and 65.5 MPa, respectively. A comparison is made of the properties with rupture strength of other kinds of rocks. The engineering geological significance of mylonites in ductile shear zones is discussed.
