| 摘 要： | 通过对沙柳沙障的质量损失率和抗折强度损失率2个指标的研究,分析了障边不同垂直位置、不同障边位置、不同坡位和不同障龄沙柳沙障的腐烂程度。结果表明：在垂直位置上沙柳沙障腐蚀的变化规律为地下部分的腐蚀程度比分界处和地上部分的高,从沙障底端到上端呈先降后升的趋势;在同一障格内障边两端的腐蚀程度偏高;在不同坡位中迎风坡坡底和坡中的腐烂程度最为严重,背风坡坡中的腐烂程度最轻;2002和2006年铺设的沙柳沙障腐蚀明显,2007年铺设的只有地下部分腐蚀发霉情况。

| Abstract: | Through studying mass loss rate and loss rate of flexural strength of Salix psammophila checkerboard,the rotten degree of Salix psammophila checkerboard at different vertical location,different border location,different slope position and different ages have been analyzed.The results show： at the vertical position,the corrosion degree of the underground part is higher than the one of overground part and the boundary part,with a tendency of decrease first and then from the bottom part to the upper part;in the same checkerboard,the corrosion degree is higher at both ends of edge;at different slope position,the most serious corrosion degree is at the bottom and the middle of windward slope,with the lowest corrosion degree in the middle of leeward slope.The corrosion of Salix psammophila checkerboards built in 2002 and 2006 are obvious,and the Salix psammophila checkerboard built in 2007 become mildewed in the underground part only. |
