| 摘 要： | 介绍并列铰接空间地基梁法的理论推导过程，结合山东八里湾船闸工程实例，分别运用并列铰接空间地基梁法、平面截条法、有限元法3种方法计算闸首底板内力并进行对比分析，结果表明并列铰接空间地基梁法比平面截条法更接近有限元法的计算结果，验证了并列铰接空间地基梁法的可靠性，可以推广应用到船闸闸首底板、水闸底板等基础梁板的设计分析中。

| Abstract: | This paper introduces the theory derivation of juxtaposed hinged spatial foundation beam method, and then with the Shandong Baliwan lock project example, the internal forces of the lock head floor are calculated by using juxtaposed hinged spatial foundation beam method, plane cuttingstrip method and finite element method respectively. The results show that the calculation results by juxtaposed hinged spatial foundation beam method are more close to that by finite element method than that by traditional plane cutting-strip method. It is proved that the juxtaposed hinged spatial foundation beam method is reliable and can be applied to the design of the lock head floor, sluice plate foundation beam plate. The method can also significantly improve the design efficiency and effectively guarantee the design quality. |
