摘要
新疆是个多山地区,地形复杂,高山与盆地相间,形成明显的地形单元。特殊的地理环境使得新疆水资源分布不均,中高山区是水资源径流的高值区,而低山丘陵区、平原区则是水资源径流的低值区和散失区,因此就使得很多引水渠道等建筑物不得不傍山而建,而坡积物又恰恰形成于山坡。本文以新疆清河灌区新建引水总干渠为例,对如何处理傍山渠道坡积物地基提出几种方案,并就处理坡积物基础的问题提出一些观点,供大家探讨。
Xinjiang is a mountainous area with complex terrain.Mountains and basins are crossed.Obvious terrain units are formed.Special geographical environment leads to uneven distribution of water resources in Xinjiang.Middle and high mountainous areas are high value area of water resources runoff.Low hilly land areas and plain areas are low value area and dissipation area of water resources runoff.Therefore,many water diversion tunnels and other buildings must be constructed besides mountain.Slope wash is just formed on the mountain slope.In the paper,newly-constructed water diversion main channel in Xinjiang Qinghe Irrigation area is adopted as an example for proposing several plans for handling mountain channel slope wash foundation.Some views are proposed aiming at handling slope wash foundation for discussion.
