摘　　要：文中以荆州城区淤泥质粉质黏土为研究对象,按照一定配合比制作水泥土试块,通过室内无侧限抗压强度试验,研究3种水泥标号、3种水泥掺入比和3种养护龄期在0.75水灰比下对水泥土无侧限抗压强度变化的影响规律。研究结果表明,水泥标号P·O42.5的水泥土抗压强度大于P·C 42.5和M 32.5的水泥土,且随着水泥掺入比和养护龄期的增加,抗压强度逐渐增大,在水泥掺入比20%和养护龄期28d的情况下抗压强度最大。This paper taking the silt silty clay in Jingzhou city as the research object,the cement soil test block is made according to a certain mix ratio,and through the indoor unside limited compressive strength test,the change law of 3 kinds of cement grade,3 kinds of cement incorporation ratio and 3 kinds of cement maintenance age is studied.The results show that the compressive strength of cement grade P·O 42.5 is greater than that of P·C 42.5 and M 32.5,and with the increase of cement incorporation ratio and curing age,and the cement incorporation ratio is 20%and the curing age is 28d.
