| Abstract: | 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. |
