摘　　要：传统围堰技术在应对高强度水流压力和不稳定河床时存在不足,迫切需要应用新的施工技术来解决这些问题。文章以某水利水电工程项目为例,研究了锁扣钢管桩与拉森钢板桩组合式围堰施工技术,以应对设计要求和复杂的水文地质条件。该组合技术充分利用了两种材料的优势,显著提升了围堰结构的刚度和稳定性,有效减少了内支撑层数,缩短了施工周期,降低了施工成本,提高了围堰工程的安全性和可靠性。Traditional cofferdam technology has shortcomings in dealing with high-intensity water flow pressure and unstable riverbeds,and there is an urgent need to apply new construction techniques to solve these problems.The article takes a certain water conservancy and hydropower project as an example to study the construction technology of combined cofferdam with locking steel pipe piles and Larson steel sheet piles,in order to meet design requirements and complex hydrogeological conditions.This combination technology fully utilizes the advantages of two materials,significantly improving the stiffness and stability of the cofferdam structure,effectively reducing the number of internal support layers,shortening the construction period,reducing construction costs,and improving the safety and reliability of the cofferdam project.
