【摘要】 为研究聚苯乙烯轻质混合土在海岸工程、堤防工程等建设项目中作为筑堤材料的可行性,通过对不同配比聚苯乙烯轻质混合土渗透性能的试验研究,得到了聚苯乙烯轻质混合土渗透系数的大致范围及其随配比变化规律,渗透系数大约在10-6~10-7cm/s之间变化,随水泥掺入比增高、龄期延长、密度变大而有所降低,降低的幅度因配比不同而异,认为轻质混合土抗渗透性能较好,可在沿海工程建设中使用。更多还原

【Abstract】 A light heterogeneous soil mixed polystyrene（LHSMP） is a new type of geomaterials,the study of its seepage properties can not be found easily in published literatures.In present study,they were studied based on laboratory seepage tests. Through the study on seepage characteristic of different ratio of LHSMP,approximate seepage coefficient and its variational principles on different ratio are found.The seepage coefficient is 10^-7 to 10^-6,the seepage coefficient of LHSMP decreases with increasing of cement content,age and density,but the degree of decreasing in the seepage coefficient varies with mixture ratio.The resntts are useful for LHSMP as embankment materials in coast construction and other engineering fields.更多还原
