摘要
膨胀土渠道处理形式多样,设计与施工难度大,造价高。对膨胀土渠道衬砌的稳定性与变形机理进行研究的基础上,分析含水量控制、缓冲层设置、护坡处理效果、设计方法等,认为在膨胀土渠道衬砌设计中不能单纯采用防渗封闭措施,在采取缓冲保护措施后,不需要另外设置防渗和排水措施,从而可以大大简化衬砌结构,降低工程造价。
Expansive soil canal has a variety types of treatments, its design and construction is in great difficulty with high cost. On the basis of research on the stability and deformation mechanism of expansive soil canal lining, the control of wa- ter content, establishment of buffer layer, effect of slope protection treatment, design method and so on are analyzed in the paper. The authors believe that the treatment of seepage control and blockage can＇ t be adopted independently, after taking the cushioning protective measures, it needn＇ t to install seepage control and drainage in addition which may greatly simplify the lining structure and reduce the cost of construction.
