中文摘要	面对种类繁多的固沙材料,通过对固化沙体基本强度特征的研究,筛选出优良固沙材料并应用到沙漠的治理中。针对引进的7种化学固沙剂,进行固化沙体抗压强度、抗剪强度、老化等基本性能测试。结果表明:固沙剂施用量为30 kg/666.7 m~2时只有石家庄、任丘抗压强度在1 MPa以下,其他5种固沙剂抗压强度都在1 MPa以上;施用量为40、50 kg/666.7 m~2时抗压强度都在1 MPa以上;固化沙体剪切强度为0.240 2~2.575 5 MPa;固沙剂与施用量、剪切强度之间存在直线关系;经历0~300 h间断照射后,7种固沙剂质量的损失率为0.2%~1.9%。初步筛选以北京、旱宝贝、文安、威海4种固沙剂较好,不同固沙剂的其他性质需要进一步试验验证。
英文摘要	To select excellent sand solidification agents suitable for desertification control, the basic characteristics of compressive strength, shear strength and ageing test of consolidated sand were conducted with 7 kinds of chemical sand solidification agents. The results showed that at the application intensity of 30 kg/666.7 m~2, the compressive strength was lower than 1 MPa only in Shijiazhuang and Renqiu agent, but the others all above 1 MPa; at the application intensity of 40 and 50 kg/666.7 m~2, the compressive strength of all was above 1 MPa. The shear strength was between 0.240 2 and 2.575 5 MPa. There was a linear relationship between application intensity and shear strength. After 0-300 h interrupted shining, the variation of weight of 7 kinds of chemical sand solidification agents was between 0.2%-1.9%. Solidification agents named Beijing, Hanbaobei, Wenan and Weihai were relatively better. The result gives the reference for the selection of sand solidification agent in desertification control.
