软土地基上失稳围堤修复措施研究

Restoration measure for unstable causeway on soft clay foundation

软土地基上的临时围堤,通常由于地质条件差、加荷速率过快等多种因素会影响围堤的整体稳定,从而易发生失稳事故。介绍了某工程临时围堤失稳所采取的修复措施,并通过对地基承载力及围堤整体稳定性的分析,探讨了软土地基上失稳围堤修复措施的关键因素,对预防失稳发生及在失稳发生后宜采用的修复措施提出了一些建议,为今后类似工程提供参考。

Instability accidents of temporary causeways on soft clay ground easily occur due to a variety of factors such as poor geological conditions, excessive rate of loading, etc., which affect the overall stability. This paper describes the repair measures taken in instability accidents of temporary causeways in a project. Based on the analysis of the bearing capacity of foundation and overall stability of causeway, this paper probes into the key facts of repair measures for instability causeway on soft clay ground. Some proposals are put forward on preventive and repair measures in instability accidents to provide reference for similar projects in the future.
