【摘要】 在不同的水泥掺入比、龄期、压实度条件下,研究了夯实水泥土渗透性能,结果表明:压实度较小时,水泥的掺入比越大,渗透系数越大;达到一定压实度时,渗透系数随着水泥掺入比的增大而减小;水泥掺入比相同时,夯实水泥土渗透系数随着龄期的延长和压实度的增大而减小;水化初期夯实水泥土的渗透系数降低较快,28 d龄期后,渗透系数降低速率较缓。更多还原

【Abstract】 In order to study the permeability coefficient of compacted cement soil,in the condition of different cement mixing ratio,age of concrete and degree of compaction,the influences of permeability coefficient,age of concrete,and degree of compaction of compacted cement soil were analyzed.The results show that when the degree of compaction is smaller,the cement mixing ratio and permeability coefficient are greater;when it achieves a certain degree of compaction,the permeability coefficient decreases with the increase of cement mixing ratio;when the cement mixing ratio is the same,with the prolong of age of concrete and the increase of degree of compaction,the permeability coefficient of compacted cement soil decreases;at the initial stage,the permeability coefficient of compacted cement soil decreases quickly,but decreases slowly 28 days later.更多还原
