摘　　要：为研究剑麻纤维结合某离子型固化剂对长春地区典型粗粒土的固化效果,配制了纤维掺量为0.6%、纤维长度为1 cm、固化剂掺量为0.03%、水泥掺量为5%的剑麻纤维水泥加固土。对加固土的无侧限抗压强度、间接抗拉强度、冻稳定性和水稳定性等路用性能指标进行了系统的试验,得出剑麻纤维水泥加固土作为路面基层材料具有早期强度高,抗弯拉性能、冻稳定性能、水稳定性能好的结论,适合在长春及其气候、土质相似地区的道路工程中应用。In order to investigate solidification effect to coarse-grained soil in Changchun by sisal fiber and ionic soil stabilizer with cement,Sisal fiber cement reinforced soil sample was prepared in which the fiber content is 0.6%,fiber length is 1 cm,stabilizer content is 0.03%,and cement content is 5%. The tests on the road performance indexes,such as the unconfined compressive strength,indirect tensile strength,frost stability,etc.,are carried out systematically. Experimental results indicate that the soil stabilized by sisal fiber and ionic soil stabilizer with cement has high early stage strength,well flexure-tension resistant performance and well frost stability. Such sisal fiber cement reinforced soil is especially suitable for Changchun and any other regions where the climate and sorts of soil are similar.
