Paper Abstract

The model selection for the chamber structure of large-scale navigation lock has a great influence on the quantities of chamber. This paper combines with an actual engineering to analysis the chamber structure of navigation lock with the help of 3D finite element. The analysis result shows that the chamber structure with double-hinges bottom board can reduce the thickness and reinforcement quantity of center inner bottom plating, bending moment of center inner bottom bottom plate is smaller than other times, because the chamber wall can't transfer bending moment to center inner bottom plate with the role of hinges. The chamber structure with monolithic bottom board which is pointed construction joints also can reduce reinforcement quantity and engineering investment by decreasing span moment of center inner bottom plate, considering the weights of chamber wall and back fill has effects on the preloading of foundation in internal force analysis of the chamber structure.
