水泥改良海相沉积淤泥质软黏土无侧限抗压强度试验研究

结合渤海近海口软基处理工程，对水泥改良海相淤泥质软黏土（即水泥土）分别在不同水泥掺量、不同龄期和不同养护条件下进行室内无侧限抗压强度试验。研究结果表明:水泥土无侧限抗压强度随着养护龄期和水泥掺入比的增加而增加；无侧限抗压强度增长速率随着养护龄期的增大而减小；标准养护条件下的水泥土无侧限抗压强度略低于自然养护条件的强度。

Study on Cement Modified Marine Sediment Silty Soft Clay by Unconfined Compressive Strength Test

In relation to the offshore soft foundation treatment engineering at Bohai Sea,the indoor tests of the cement modified marine soft clay (i.e.cement soil) were conducted under different cement content and different curing age and conditions. The result shows that, the unconfined compressive strength of cement soil increases with the increment of curing age and cement content; the increasing speed of the strength decreases with the increment of curing age; under the standard curing conditions, the strength is slightly lower than that under natural curing conditions.
