摘    要:采用新研发的数字化冲刷试验仪(动水压力、速度和入射角度等可调),开展了水泥稳定土和水泥稳定碎石这2种基层材料的室内冲刷试验,得到了水泥稳定类基层材料冲刷深度与冲刷次数、动水压力以及材料无侧限抗压强度之间的相互关系,其中,冲刷动水压力与材料无侧限抗压强度之比对其抗冲刷能力影响最大.研究成果可作为制定基层材料抗冲刷性能试验方法的依据.

关 键 词:路面工程  水泥稳定类基层材料  抗冲刷性能  冲刷动水压力  冲刷深度

Abstract:By using a brand new digital testing equipment, the erosion resistance performances of two commonly used base materials, such as cement stabilized granular and cement stabilized soil, were studied. The erosion depth of cement stabilized base materials is closely related to the erosion cyclic number, hydrodynamic pressure as well as the unconfined compressive strength, among which the ratio of hydrodynamic pressure to the unconfined compressive strength is a crucial factor to affect the erosion resistance performances of cement stabilized base materials. However, the research may be used to formulate the procedure of erosion resistance performance testing for base materials.
Keywords:pavement engineering  cement stabilized base material  erosion resistance performance  hydrodynamic pressure  erosion depth
