摘　　要：针对红黏土这种特殊土质,研究了水泥掺量、龄期、Ca(OH)2掺量等对水泥红黏土无侧限抗压强度的影响。结果表明:水泥红黏土的无侧限抗压强度随着龄期的延长而增强;水泥土无侧限抗压强度随着水泥掺量的增加逐渐增强,15%的水泥掺量为最优掺量;Ca(OH)2对水泥红黏土无侧限抗压强度影响较大,随着Ca(OH)2掺量的增加强度增强。In view of this special red clay,the effect of cement content,age,Ca（OH）2 dosage changes on unconfined compressive strength of red clay cement were studied.The results show that with the increase of the age the unconfined compressive strength of red clay cement increases;with the increases of cement content the unconfined compressive strength of red clay cement increased,the 15% of the cement content is the optimal dosage of red clay cement;the effect of Ca（OH）2 on the unconfined compressive strength of red clay cement is great,with the increased of Ca（OH）2 dosage the unconfined compressive strength of red clay cement increases.
