摘要
采用紫外光耐气候老化试验箱模拟经硬挺整理的纯棉沙障的自然老化过程,分别研究光照温度及老化时间对纯棉沙障断裂强度和弯曲长度的影响。试验结果显示,在模拟的36个月的老化时间内,随着光照温度及老化时间的增加,纯棉沙障的断裂强力降低,弯曲长度增加,但断裂强力仍在有效范围内。
The natural aging process of stiffened cotton sand barriers was simulated by using the UV light weathering test chamber,and the effects of light temperature and aging time on the breaking strength and bending length of cotton sand barrier were studied respectively.The test results showed that,in the simulated aging time of 36 months,with the increase of light temperature and aging time,the breaking strength of cotton sand barrier decreased and the bending length increased,but the breaking strength was still within the effective range.
