本文介绍复杂地基上多级船(筏)闸的光弹性应力分析。扼要阐述了异弹模组合模型浇制与粘结以及荷载模拟与加载方法。系列的模型试验给出了包括闸室和主廊道所受各种不同荷载组合的应力成果。 文中对不同边界条件下闸室工作特性及应力状态作了分析比较,探讨了它们的主要差异和相互关系,论述了双侧嵌固时闸室的应力分布规律,讨论了一侧嵌固、另侧自由时对结构受力的不利影响以及改进途径与措施。
This paper introduces the photoelastic stress analysis of a multi-stage vessel (sluice) gate on a complex foundation. This paper describes the casting and bonding of the different elastic-mold combination models and the load simulation and loading methods. A series of model tests gives the stress results including various combinations of load on the lock chamber and the main corridor. This paper analyzes and compares the operating characteristics and stress state of the chamber under different boundary conditions, discusses their main differences and mutual relations, discusses the stress distribution law of the chamber when both sides are embedded, and discusses one side of the chamber and the other. The adverse effects of lateral freedom on structural forces and the ways and measures to improve them.
