龙溪口航电枢纽右岸接头坝方案比选

施工设计优化在船闸施工设计中的运用越来越广泛，以龙溪口项目右岸接头坝为例，综合考虑工程边界条件，提出右岸接头坝3种实施方案比选。从工程质量风险、施工工期和施工成本等方面进行比选，同时考虑右岸接头坝工期紧张、基础处理难度大等特点，选择最佳实施方案。在实施运用中，针对右岸接头坝建设中的重难点，采取了一系列优化技术与措施，保证工期的同时将成本降至预期效果。

Scheme comparison of right bank joint dam of Longxikou Navigation-power Junction

Construction design optimization is more and more widely used in the construction design of ship locks.Taking the right bank joint dam of Longxikou project as an example,considering the engineering boundary conditions comprehensively,three kinds of implementation schemes for the right bank joint dam are proposed.The best implementation plan is selected from the aspects of project quality risk,construction period and construction cost,and the characteristics of tight construction period and difficult foundation treatment of the right bank joint dam are considered.In the implementation and application,a series of optimization techniques and measures have been taken to ensure the construction period and reduce the cost to the expected effect in view of the difficulties in the construction of the right bank joint dam.
