摘  要：
为了修复雅砻江两河口水电站工区受损陆地边坡,通过对植被混凝土掺入不同质量配比的棕纤维和黄麻纤维进行冻融循环试验。结果表明,植被混凝土的质量损失率随冻融循环次数的增加呈线性增加,相对质量损失率随冻融循环次数的增加呈先增大后减小的趋势;质量损失率和相对质量损失率随着掺入纤维质量比的增加均呈先增大后减小的趋势,当棕纤维和黄麻纤维的质量配比分别为0.6%和0.9%时,损失均最小;同时对植被混凝土的质量损失率和相对质量损失率的计算结果分别对两种纤维做敏感性分析,表明棕纤维的敏感性高于黄麻纤维。

摘  要：
In order to repair the damaged slope land in Yalong River Lianghekou hydropower station work area, the freeze-thaw cycle experiment was conducted through mixing the vegetation-growing concrete with palm fiber and jute fiber of different quality ratio. The results showed that mass loss rate of the vegetation-growing concrete linearly increased with the increase of freeze-thaw cycles, relative mass loss rate with the increase in the number of freeze-thaw circulation firstly increased and then decreased;mass loss rate and relative mass loss firstly increased and then decreased with the increase of doped fiber quality, when the quality ratio of paln fiber and jute fiber were 0.6% and 0.9% respectively, losses were minimal. At the same time, by the quality of the vegetation-growing concrete loss rate and relative mass loss of the calculation results, the sensitivity analysis for two kinds of fibers were conducted, the results showed that the sensitivity of the palm fiber was higher than that of jute fiber.
