| 摘 要： | 结合柱状节理玄武岩块室内直剪试验和现场大尺度直剪试验所取得不同尺度岩块的抗剪参数试验成果，进行异计拟合回归分析得到柱状节理玄武岩体抗剪强度参数内聚力c和内摩擦系数f的尺寸效应经验表达式，认为抗剪强度参数与试样尺寸间近似呈幂函数形式。抗剪强度参数的表征单元体积研究表明，内聚力对试样的尺寸更为敏感。

| Abstract: | This paper is based on the results of in-situ and laboratory direct tests of basalt rock mass with columnar joints.Allometric curves are fitted with the test data and empirical formulas are obtained about the shear strength of the basalt rock mass with columnar joints.The analysis shows that the values of the cohesion c and the internal frictional coefficient f vary approximately with the size of test samples as power functions.The representative elementary volumes of the c and f are analyzed.The cohesive f... |
