摘要
堆石料的浸水变形是引起土石坝后期变形的主要因素之一。为了研究不同试验方法对堆石料湿化变形的影响,采用大型压缩仪对五通组堆石料进行了单线法和双线法湿化试验,研究了一维湿化变形条件下单线法和双线法对试验成果的影响,比较了两种试验条件下堆石料的湿化变形规律及湿陷系数,根据试验结果建议采用采用单线法对堆石料湿化特性进行研究。
The wetting deformation of rockfill is one of the main factors causing the deformation of earth and rockfill dam.To analyze the influence of different test methods on wetting characteristics of rockfill materials,wetting tests on Wutong rockfill materials are performed by a large compression apparatus based on the single-line method and the double-line method.The different influences on one-dimensional wetting characteristics of rockfill materials between the single-line method and the double-line method are analyzed,the wetting characteristics and collapsibility coefficients of two different methods are compared.According to the test results,the single-line method is proposed to analyze the wetting character-istics of the rockfill materials.
