| 摘 要： | 京杭大运河某船闸工程位于山东与江苏交界的苏北地区,是运河上的重点船闸建设工程。由于工程所在地岩土地质勘察资料不完整和船闸驳岸挡土墙结构设计时采用了较低的安全系数,因而在运行期间发生局部滑移变位,使得整个船闸的安全性受到很大影响,必须对原有驳岸挡土墙进行修护加固。主要针对船闸出现的驳岸挡土墙滑移事故,采用理论分析对比和建立数学模型简化计算的方式,进行修护方案的设计与可行性研究,提出阻滑板和加筋土两种方案。从安全性角度对该方案对比分析,最终确定驳岸挡土墙的修护加固方案,为类似工程提供技术参考。

| Abstract: | The shiplock works located on the Beijing Hangzhou Grand Canal at the junction of Jiangsu and Shandong Provinces is one of the most important shiplock works. In the design of shiplock works, due to lack of geological investigation data and the lower safety factor applied to the design of the revetment retaining wall, there occurs a local sliding deformation during the shiplock operation, which may have a danger to the entire safety of the shiplock. It is necessary to make repair and reinforcement of the existing revetment retaining wall for the safety of the shiplock. Considering this sliding failure, the feasibility of the repair-reinforcement scheme for the revetment retaining wall is studied based on theoretical analysis and simplified numerical simulation. Through the simulation calculation and optimization analysis, two kinds of schemes of the slide-resistant slab combined with the reinforced earth have been put forward in this study. From the angle of the safety of the wall works, comparative analyses are carried out for the schemes, and finally the scheme of the slide-resistant slab combined with the reinforced earth is determined as a repair-reinforcement scheme for the revetment retaining wall. The research and analysis of the works can be taken as a technical reference for dealing with the slide-resistant stability of the similar works. |
