摘要
结合长江口袋装砂筑堤工程实践,从加筋机理、破坏模式、计算方法等方面,探讨了袋装砂围堤的稳定性;从袋体材料的选择及抗老化试验等方面,分析了袋装砂围堤的可靠性;针对袋装砂围堤的应用现状,从袋装砂围堤设计与规范的协调以及袋装砂围堤耐久性等方面,提出了尚需进一步研究的问题。在技术上为推进袋装砂围堤的广泛应用提供了理论支撑和实践依据。
In the combination with the engineering practice of dike construction by bagged-sand in Yangtze River estuary, the stability of the bagged-sand dike is demonstrated in terms of the reinforcement mechanism, failure mode, calculating methods etc. The reliability of the bagged-sand cofferdam is analyzed from the perspective of bagged-sand material＇s selection and anti-aging tests etc. The future research issues are put forward from the aspects of coordination between the bagged-sand cofferdam design and relative technical code as well as the durability. The theoretical and practical basis is provided for wide application of bagged-sand cofferdam.
