摘要
采用不同天气下的原位及室内试验方法,对广东云浮地区粉状煤系土的工程地质性质进行了测试,系统研究了煤系土的物理力学特性,重点论述了粉状煤系土不同干密度、不同含水率下抗剪强度和现场静力触探比贯入阻力的变化规律,提出了粉状煤系土的多项强度指标,建立了具有实用参考价值的经验性公式。研究结果为合理评价粉状煤系土的特性、路基处理和边坡处治提供理论依据,具有一定的实际意义。
According to the results of tests in laboratory and in-situ under different weather conditions, the geotechnical properties, some laws of different dry densities and original water content shear strength properties and penetration-resistance of static cone sounding of in-situ of the powdered soil of coal measure strata are discussed emphatically. Some important critical indices of the powdered soil of coal measure strata are put forward. And the empirical formulas with practical value are given. The research results would provide theoretical reference for evaluating properties, roadbed treatment and slope treatment of the powdered soil of coal measure strata.
