中文摘要	以石膏基固沙材料为研究对象,对其固结层的抗冻融、耐老化、抗风蚀、野外应用进行了试验研究。结果表明:该材料在经历20次连续冻融循环后强度仍有1.56 MPa,在经历500 h连续紫外辐射后外观无变化,强度损失只有22.94%;随着风速和坡度的增加,风蚀量增大,风蚀率最高值为0.2016 g/(min ? m~2),相对较小;4个月风吹日晒后外观无变化。该固沙材料具有良好的耐候性能,在沙漠治理方面具有广阔应用前景。
英文摘要	The freeze-thaw resistance, aging resistance, wind erosion resistance and the field application of gypsum-based sand-fixing material were tested and measured. The result showed that the strength of the materials after 20 successive freeze-thaw cycles was 1.56 MPa,the appearance had little change and intensity loss was only 22.94% after 500 h consecutive ultraviolet radiation. With the increase of wind speed and slope, the amount of erosion increased, the erosion rate increased, the highest erosion rate reached 0.2016 g/(min ? m~2). The appearance had little change after four month exposion to the weather. This material has good weather resistance property, and it will have a wide application prospect in the desert governance.
