【摘要】 对不同比例的掺土煤矸石试样在室内进行了一系列的力学性能研究,为煤矸石在高速公路工程中的应用提供科学依据.研究结果表明,在煤矸石中掺加适当比例的粘土,可以提高煤矸石的抗剪强度,改善煤矸石的稳定性与压实性.表明掺土煤矸石满足路堤填筑材料对力学性能的要求,将掺土煤矸石应用于高速公路工程是可行的.更多还原

【Abstract】 The mechanical properties of the mixed soil coal gangue sample with different proportions have been studied,which provides a scientific basis for its application to the express way construction.The results indicat that the coal gangue mixed with appropriate proportion of clay can improve the sheer strength of coal gangue and its stability and compaction,meanwhile can meet the requirements of the embankment filling materials on the mechanical properties.Therefore,it’s feasible to apply mixed soil coal gangue to the highway engineering.更多还原
