煤矿软岩抗剪强度参数与含水量关系试验研究

Experimental Study on Relationship Between Water Content and Shear Strength Parameters of Soft Rock in Coal Mine

  • 摘要: 通过对原状试样和重塑试样的直接剪切试验来研究抗剪强度及其参数与含水量的关系。研究发现:原状试样中,随着含水量的增加,抗剪强度呈指数下降;黏聚力和内摩擦角与含水量的关系可以用指数函数描述。重塑试样中,含水量对黏聚力的影响比内摩擦角显著。黏聚力随含水量的增加呈先增大后减小的趋势,内摩擦角随含水量的增加呈不稳定波动。研究结论在某露天煤矿东帮软岩边坡工程治理中得到了应用。
    Abstract: This paper mainly studies the relationship between water content and shear strength and shear strength parameters by direct shearing with undisturbed samples and remodeling samples. The research shows that shear strength decreases exponentially with the increase of water content and the relationship between water content and cohesion and internal friction angle can be expressed by exponential function in undisturbed samples. The influence of water content on cohesion is more significant than internal friction angle. Cohesion increases at first, then decreases with the increase of water content and internal friction angle is in a state of unstable fluctuation in remodeling samples. The conclusion has been applied to soft rock slope treatment in east slope in some open-pit coal mine.
