摘要
在人类活动和自然因素的综合作用下,珠江三角洲河床大幅度下切,对该地区取水工程选址影响显著。以拟建的番禺区生活垃圾综合处理厂取水口工程选址论证为例,该工程位于珠江三角洲上横沥水道左岸大岗镇,通过采用实测水文和地形资料分析、数学模型计算等方法,对上横沥水道河床演变规律及工程附近河段水流流态进行综合分析,从而为工程取水口的选址提供了依据,并提出了针对珠江三角洲河床下切现状取水口的选址原则,可为今后类似取水工程选址提供借鉴。
Serious riverbed undercutting appears in the Pearl River Delta due to the combined effects of human activities and natural factors, which has influenced the site selection of water intake projects significantly in this area. In this paper, the site selection of water intake projeet for a domestic waste treatment plant at the left bank of Shanghengli channel, in Panyu District of Guangzhou City, was taken as an example, the fluvial process of Shanghengli channel and flow regime of the river reach were an- alyzed through analysis of the observed hydrological data and numerical simulation. As a result, the basis for site selection of wa- ter＇ intake project was provided and the principles for the site selection in view of the riverbed undercutting in the Pearl River Del- ta were proposed.
