三峡工程库区移民中，大部分属于城镇移民。三峡水库正常蓄水位１７５ｍ，水位变幅达３０ｍ，新城镇建设在高程１８２ｍ以上。供水工程相对独立、规模较小，与武当山供水工程具有相同的工程特点和技术特性。结合武当山供水工程实例对大变幅超吸程取水工程的优化问题进行有益的探讨；从具体情况及工程实际出发，提出了切实可行的优化方法和安全可靠的工程技术措施；成功地解决了供水工程大变幅超吸程的吸上取水和小流量高扬程的水锤防护等工程技术难题；为三峡库区城镇供水提供了有价值的参考。
Among the resettlers in the reservoir area of the Three Gorges Project, most belong to urban migrants. Three Gorges Reservoir normal water level 175m, water level amplitude of 30m, the new town construction elevation 182m above. Water supply project is relatively independent, smaller, and Wudang Mountain water supply project has the same engineering features and technical characteristics. Combining with the Wudangshan water supply project example, this paper discusses the optimization of the water pumping project with large amplitude and the superabsorber water. Based on the actual situation and engineering practice, the feasible optimization method and safe and reliable engineering measures are put forward. Water supply project Supra Suction Suction Suction Suction and low flow high-lift water hammer protection and other engineering technical problems; for the Three Gorges reservoir town water supply provides a valuable reference.
