摘要
针对新疆伊宁县麻扎灌区渠道改造工程,设计了梯形、矩形和U形共3种断面结构型式的渠道,并基于模糊综合评价分析法对3种渠道结构型式进行对比分析。结果表明,梯形渠道在工程投资上表现最佳,而U形渠道在施工进度和抗冻性方面表现最佳;以工程投资、施工进度、抗冻胀性作为模糊综合评价因素,U形渠道为麻扎灌区最佳的渠道结构型式;梯形渠道在优先考虑抗冻胀性时刻作为第二选择,矩形渠道在优先考虑施工进度时可作为第二选择。
Aiming at the channel reconstruction project of Mazha irrigation area in Yining County,Xinjiang,three cross-section structure types of channels are designed,including ladder type,rectangular type and U-type,and the three channel structure types are compared and analyzed based on fuzzy comprehensive evaluation analysis method.The results show that the ladder channel performs best in engineering investment,while the U-channel performs best in construction progress and frost resistance;taking project investment,construction progress and frost heave resistance as fuzzy comprehensive evaluation factors,the results do not show that U-shaped channel is the best channel structure in Mazha irrigation area;ladder channel is the second choice when giving priority to frost expansion resistance,and rectangular channel can be the second choice when giving priority to construction progress.
