摘　　要：针对我国半干旱区高速公路边坡生态恢复治理TBS技术中的基材性能进行了5个方面的研究,即进行了基材保水剂施用量对比试验、黏结材料用量、基材含水量的确定、基材质地分析和容重分析、基材pH值变化分析等研究。研究结果表明,该技术中配制基材的各项性能均达到了项目要求标准。本文对该技术的推广运用在理论上提供了支持。TBS technology is an effective method in the ecological restoration of expressway slope. Of which, base material is absolutely the key technique, the detailed experimental studies on the properties of base material are made, including absorbent polymers dosage, binder dosage, base material moisture analysis, base material texture and bulk density analysis, and base material pH value change analysis. The results indicate that the five properties of base material reached the required standard of the project, and had gotten excellent application effect in demonstration engineering. It offers some technical support for the popularization of the TBS technology.
