从力学及路用性能的角度出发,进行SEU-2型固化剂和其他材料加固粉质土路基的室内及现场试验研究,以确定加固粉性土路基的合理方案及外加剂掺量,并对其稳定规律进行分析。研究结果表明,掺加SEU-2型固化剂可明显增加粉性土的无侧限抗压强度和水稳性,减小其收缩变形。掺加4%SEU-2型固化剂能满足路基的各项技术指标要求,是最为合理的加固粉性土路基的方案。
From mechanics and road performance point of view, the SEU-2 curing agent and other materials to strengthen the silty soil subgrade laboratory and field experiments to determine the reasonable reinforcement powder soil subgrade and admixture dosage, and The stability of the law for analysis. The results show that the addition of SEU-2 curing agent can significantly increase the unconfined compressive strength and water stability of silt soil, reduce its shrinkage deformation. Addition of 4% SEU-2-type curing agent to meet the technical requirements of the subgrade, is the most reasonable reinforcement of soil subgrade program.
