川中红色砂泥岩岩石力学特性研究

ON THE ROCK MECHANIC PROPERTICS OF MUDSTONES AND SANDSTONES IN THE MIDDLE PART OF SICHUAN RED BASIN

对川中白垩系、侏罗系的泥岩、砂岩、泥质粉砂岩的抗压强度进行统计分析 ,得出红层岩石作为地基时抗压强度的范围值供设计参考 ,对泥岩、砂岩的其他力学性质进行了评价。

WT5”,6BZ]Through statistical analysis of the rock mechanic properties of upper Jurassic and Cretaceous red mudstones, siltstones and sandstones in the middle Sichuan Red Basin, the range of their compressive strength, the features of the shearing strength and of the deformation curves are proposed in this paper.
