| 摘 要： | 选取怒江段、高黎贡山隧道和潞西—平达段的灰岩、砂岩、花岗岩、玄武岩4种岩性,分别进行了岩石抗压强度、抗剪强度、抗拉强度、弹性模量、泊松比等力学性能参数的实验室和室外现场测定。结果表明,岩石力学参数的定量测试与野外岩组的定性划分、理论依据能很好地吻合。通过野外实地观察,结合岩石样品力学性质参数的室内测试和室外现场测定,对大理—瑞丽铁路沿线的工程地质岩组进行了划分,共划分出22个工程地质岩组。在全线工程地质岩组中,坚硬岩组占16.23%,坚硬—较坚硬岩组占31.67%,较坚硬岩组占26%,较坚硬—较软弱岩组占14.17%,软弱岩组占11.93%。全线以坚硬和较坚硬岩组为主体。

| Abstract: | Based on studying the mechanical properties of the rock mass along the Dali-Ruili railway,such as compressive strength,shear strength,tensile strength,elastic modulus and Poisson＇s ratios,the authors have found that the mechanical properties are well consistent with the theory and the field rock mass classification.Combining the field investigation with the tests of the rock mechanical properties,the authors classified the engineering geological rock masses along the Dali-Ruili railway into 22 groups,in which the hardest and harder rock mass groups occupied the major proportion. |
