基于Autobank渠道防渗措施模拟

Simulation of Seepage Control Measures Based on Autobank

结合某灌区实际情况,设计了渠道防渗结构形式,采用Autobank软件对防渗前后及各种防渗措施效果进行分析,得出以下主要结论:(1)经防渗措施处治后,渠道抗渗能力得以提高,水资源利用率增强;(2)与土渠相比,浆砌块石衬砌渗流减小量为56.6%,复合防渗渠道1渗流减小量为60.4%,复合防渗渠道2渗流减小量为53.9%;(3)3种防渗工程措施防渗效果差别不大,主要考虑抗冲性能、地下水位高低等要素因地制宜选择。

Based on the actual situation of a certain irrigation district, the structure design of canal seepage control is designed, the autobank software was applied to analyse the effect of channel be- fore and after anti - seepage, and the following primary conclusions has been got ： ①after the anti - seepage measures has been taken, Channels＇ anti - seepage ability has been enhanced, and the water resource utilization ratio has been increased; ②Compared with earth canal, Plasma block stone lining＇ s seepage discharge was decreased to 56. 6%, the composite impervious channel 1 ＇ s seepage discharge was decreased to 60. 4%, the composite impervious channel 2＇ s seepage dis- charge was decreased to 53.9% ; ③There was little difference between the other 3 anti - seepage measures.
