摘要
通过对防渗渠道的U形、梯形、矩形、半圆形、复合式、暗渠等断面组成及其水力学特性的对比分析,认为在防渗渠道的建设中,干、支渠应选用宽浅式梯形断面,而农渠中应选用U形断面.
Based on analysis and comparison of cross-section composition and water hydraulic properties of several seepage control canals with“U”type, trapezoid, rectangle, semicircle, compound and underdrain types,a conclusion was drawn that the wide-shallow trapezoid cross-section should be chosen in the main and branch canals,while“U”type cross-section should be selected in sub-canals.
