| 摘 要： | 采用MBER土壤固化剂和水泥,对剂量、含水率和龄期影响固化土和水泥土的劈裂抗拉强度的规律性进行了试验研究.结果表明,固化土劈裂抗拉强度在0.08～0.43 MPa,水泥土劈裂抗拉强度在0.09～0.35 MPa.在其他条件一定时,固化土和水泥土的劈裂抗拉强度随着剂量增加丽增大,劈裂抗拉强度在试件含水率为最优含水率时达到最大值；随龄期增大,固化土和水泥土的劈裂抗拉强度均有不同程度的增大.在龄期相同条件下,固化土劈裂抗拉强度略高于水泥土. |

| Abstract: | This paper studied the influences of dose,moisture content and maintenance period on splittingtensile strengths of MBER stabilized and cement stabilized soils.Results indicated that the splitting tensilestrength of MBER stabilized soil was between 0.08and 0.43MPa,and of cement stabilized soil,between0.09and 0.35MPa.When other factors remained unchanged,the splitting tensile strengths of the two stabilized soils increased with the increase in applied dose and reached the peak value at the optimum moisturecontent.The two splitting tensile strengths also increased with maintenance period.Under the same age,thesplitting tensile strength of MBER stabilized soil was slightly higher than that of cement stabilized soil. |
| Keywords: | MBER soil stabilizer stabilized soil cemented soil splitting tensile strength |
