STW型生态土壤稳定剂用于防风固沙试验研究

Experimental study on application of STW ecotypic soil stabilizer in windbreak and sand fixation

利用自主研发的STW型生态土壤稳定剂,试验研究了其用于防风固沙的力学性能和抗风蚀性能,利用超微型贯入仪和自制的模拟吹风装置对改性沙土的强度和抗风蚀性能进行了试验分析。试验结果表明:STW型生态土壤稳定剂改性沙土的强度有了明显提高,具有较好的抗风蚀效果和一定的保水性能,稳定剂的使用浓度以5%为宜。

By means of the self-developed STW ecotypic stabilizer to improve sand, the mechanical properties and weathering quality of the modified sand were investigated. The relevant data was obtained through the strength tests using the super mini-penetrometer and weathering resistance tests which utilized the self-made air blast simulator. It was indicated that the mechanical strength of the modified sand was obviously improved as well as the water retentivity and weathering resistance, and the optimal effect could be achieved when the stabilizer with the concentration of 5% was prepared.
