吐孜乌达克支渠现状为土渠,主要存在渗漏严重,渠系水利用系数低,断面不规则,输水效率低下,过流能力不足等问题。工程区位于喀河冲洪积平原中下部,地形平坦开阔。渠线地层岩性均以低液限粉土为主,局部为含沙粉土。生态林区沿线有风积沙丘及粉细砂分布。渠系建筑物未配套,致使项目区生态林不能有效灌溉。文章对该渠道渗漏问题及边坡稳定性进行了分析探讨,提出吐孜乌达克支渠渠道堆积坝坝体具有较差的稳定性,主要原因是其工程性能较差及其浸润线较高。
The status quo of the branch of the Tuzizi Utuddiaway is a soil canal, with the main problems of serious seepage, low drainage coefficient of canal system, irregular cross section, low water conveyance efficiency and insufficient overcurrent capacity. The project area is located in the middle and lower parts of the Kahe alluvial plain with flat and open terrain. Drainage line lithology are low liquid limit silt are mainly local sandy silt. The distribution of aeolian sand dunes and fine sand along the ecological forest area. Drainage system is not supporting the building, resulting in the project area can not be effectively irrigated ecological forest. The article analyzes the canal seepage problem and the stability of the slope. It is suggested that the dam body of the channel stack dam in the Tuzik branch canal has poor stability, mainly due to its poor engineering performance and high infiltration line .
