| 摘 要： | 结合具体工程实例，介绍了大跨径水闸底板的几种结构型式，分析了实体结构与空箱结构的特点并作了比较。结果表明，空箱结构底板刚度更大，自重较轻，更适合大跨径结构；实体结构底板厚度应控制在适当范围内，不宜太厚，确保底板配筋合理，施工中须严格控制裂缝的产生；空箱结构底板受力及计算更加复杂，宜同时采用结构力学方法与有限元法，保证结构安全。通过分析探讨，总结经验，可使大跨径水闸工程的底板设计得到启发，使其设计更加合理和完善。

| Abstract: | Based on engineering examples to introduce several different structure types of Large-span sluice base plate,analyze and compare the characteristics of solid and hollow structure. The result shows the hollow structure is more suitable for large-span structure because of bigger stiffness and little weight,and the thickness of solid structure base plate should be controlled in construction for structure′s safe. Structural mechanics and finite element method must be used at the same during force calculations. The results can give inspiration for large-span sluice designing and make the sluices designing more reasonable and comprehensive. |
