输水渠道由于采用了衬砌等防渗措施,对地形和纵坡有了更强的适应性,可以在满足使用要求的前提下尽可能缩短长度或提高高程,因而出现许多填方(或半填半挖)渠道,填方渠道的施工质量控制不严,在运行当中极有可能发生沉陷或溃渠,造成不应有的损失。引额济克西干渠引水工程项目属国家大II型工程,渠道全长217.184km,最大流量61m3/s,其中填方渠道(或半填半挖)长101.3km,填方量291.8万m3/s,最高处渠顶与
Waterway As a result of the use of lining and other anti-seepage measures, the topography and longitudinal slope has been more adaptable to meet the requirements of the premise can be as short as possible to increase the length or elevation, resulting in many fill (or semi-filled Semi-dug) channels, filling the poor quality control of the construction of channels, in operation are most likely to subsidence or canal collapse, resulting in undue losses. The diversion project of the Zixi trunk canal belongs to the national large-scale II project with a total length of 217.184km and a maximum flow of 61m3 / s, of which the fill channel (or half-filling and half-digging) is 101.3km with a filling volume of 2,918,000m3 / s, the highest point at the top of the canal
