| 摘 要： | 针对边坡客土层底部滯水层导致边坡失稳的问题,提出了一种用塑料盲沟进行土层底部排水的新方法.并凭借人工模拟降雨装置,对不同类型和型号的塑料盲沟在不同条件下的排水效果进行了分析和评估.实验结果表明,随雨强增大,塑料盲沟的排水量也增多,但排水效率有所下降;在大于30°的较大坡度下,塑料盲沟有较好的排水效果;中空圆形塑料盲沟在降雨过程中具排水优势,而多孔矩形塑料盲沟在降雨结束后排水效果更好;塑料盲沟能有效降低客土层土壤含水量,防止滞水层和软弱滑动面的出现,从而增强客土层的稳定性.

| Abstract: | To solve the side slope external soil instability caused by the stagnant water layer,a new method to drain water away from the external soil with the plastic blind drains implanted at the bottom was proposed.Based on artificial rainfall simulations,the drainage efficacies of different types of plastic blind drains were analyzed and evaluated under different conditions to provide theoretical guidance for practical applications.The results showed that with increased rainfall intensity,the amount of water drai... |
