摘要： 引江济汉工程是一条引长江水到汉江的特大型干渠，是南水北调中线一期工程的组成部分，引江济汉通航工程进出口处分别布置一座三级船闸，出口船闸布置在汉江右岸潜江市高石碑镇，与干渠出水口相依。通过现场抽水试验，查明了高石碑船闸主体工程场地地层结构与渗透特性，选取了合适的井型结构等有关抽水井的参数，确定一期工程的深井降水方案，对其它大型船闸基坑降水具有借鉴作用。

Abstract: The water diversion works from Yangtze River to Hanjiang River was the giant main canal and one part of mid\|route of South to North Water Diversion and there was the three level ship lock at the entrance of navigation engineering, which was located at the right side of Hanjiang River in Gaoshibei town, Qianjiang city and connected with the giant main canal. The stratum and permeability property of construction site of Gaoshibei ship lock engineering was obtained by in\|situ pumping test and the parameter of pumping well such as well structure was selected, then the deep well dewatering scheme was proposed, which was provided as a reference for similar dewatering engineering of ship lock foundation.
