摘要
水利、交通、建筑等土木工程建设中,压实填土是经常遇到的建设内容,压实填土遇降雨、水浸时,含水率逐渐增大,颗粒间结合水逐渐增厚,结晶盐类逐渐溶解,压实填土粘聚力逐渐减小,土体强度逐渐降低,严重时导致工程破坏.使用不同级配土体,按各自最优含水率击实,制备多组试样,分批次在不同条件下浸水,测定土体强度随浸水时间的变化数值,分析其变化规律、土体级配与土体强度随浸水时间降低的关系、产生原因,给出了较好的压实土种类,为水利、交通、建筑工程压实填土浸水后预防工程事故提供参考.
Compacted filling earth is widely used in construction project,and it is easily destroyed by the infiltration of water because of the decrease of the soil cohesive force and the reduce of soil strength with crystal salt dissolving.The paper introduces the experiment,in which some models of earth were prepared by their gradation and optimum compaction moisture content,and the earth strength were measured with different soaking time.The paper also analyses the reason and law between earth strength and length of soaking time,providing the reference for water conservancy,transportation,construction engineering.
