摘要
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 describes the photoelastic stress analysis of a multistage lock rested on complicated foundation as well as the casting and bond of combined model with materials of different elastic moduli, load analogy and loading method. Stress results, including a variety of loading combinations acting on the chamber and its main gallery, have been given through a series of model researches in laboratory.Performances and stress states of the lock chamber under different boudary conditions have been analyzed and compared. Their principal differences and relation have also been approached.Regularity of stress distribution in lock with both external sides built-in has been described. In addition, the disadvantageous effects on structure stress in lock with one external side built-in and another free and the ways and measures to improve such lock are also discussed.
