引江济淮工程庐江枢纽船闸布置方案优化调整

Optimized Layout for Ship Lock in Lujiang Control Diversion Project from Yangtze River to Huai River

引江济淮工程初步设计批复的庐江船闸位置处于岩土分界面上,且部分闸基处于断层破碎带处。在庐江船闸施工图设计阶段,根据详勘的工程地质报告,进一步提出了三种船闸布置方案加以比较,重点研究闸基稳定安全、能否避开断层破碎带、闸基处理措施、航道顺直程度、工程占地数量、船只进出闸型式、工程投资等技术经济指标。最终通过改变船闸的进出闸型式,适当偏移引航道,进而有效地避开了闸基断层破碎带。

The position of Lujiang ship lock in the preliminary design for the project from the Yangtze River to the Huai River approved is located at the interface of the rocks,and part of gate foundation is located at fault fracture zone.In the stage of construction drawing design for Lujiang ship lock,according to the detailed geological report for the project,everyone concerned further proposed and compared three kinds of ship lock layout schemes.A series of technical and economic subjects were studied including the stability of gate foundation,is it possible or not to avoid the fault fracture zone treatment measures for gate foundation,degree of alignment in navigation way,quantity of land occupied by the project,types of head gate and tail gate for ships,project investment,and so on.Finally through altering the types of head gate and tail gate for ships,properly deviating approach channel,thus effectively avoiding fault fracture zone under gate foundation.
