Panel dam foundation diaphragm wall structure suitable for large stress deformation
The invention discloses a concrete faced rockfill dam foundation diaphragm wall structure adapting to large stress deformation, which comprises two diaphragm walls, two connecting plates and three supporting brackets, and is arranged on the upstream side of a toe board. The toe board is connected with the first anti-seepage wall through two connecting plates, the second anti-seepage wall is arranged at the bottom of the corner of the toe board, arc-straight line joints are used between the toe board and the connecting plates and between the two connecting plates, inclined joints are used between the connecting plates and the first anti-seepage wall, and the connecting plates are connected with the second anti-seepage wall. Three supporting brackets are arranged on the downstream side of the first anti-seepage wall and the bottom of the connecting plate in total. By arranging the two anti-seepage walls, the supporting brackets, the inclined joints and the arc-straight line joints, deformation of the whole structure is limited, meanwhile, joint deformation is reduced, and the structural deformation coordination problem under the large stress deformation condition is solved. And the two connecting plates and the inclined seam are arranged, so that local stress is reduced, and the stress state of the structure is improved. A stress model of the diaphragm wall structure is established and used for calculating the maximum stress of the structure and checking the safety of the structure.
本发明公开了一种适应大应力变形的面板坝坝基防渗墙结构，包括两道防渗墙、两块连接板、三个支撑牛腿，并设置在趾板上游侧。趾板与第一道防渗墙之间使用两块连接板进行连接，趾板转角处的底部设置第二道防渗墙，趾板与连接板之间、两块连接板之间使用圆弧‑直线接缝，连接板与第一道防渗墙之间使用倾斜缝，第一道防渗墙下游侧和连接板底部共设置有三个支撑牛腿。通过设置两道防渗墙、支撑牛腿、倾斜缝和圆弧‑直线接缝限制了整体结构的变形，同时减小接缝变形，改善了大应力变形条件下的结构变形协调问题。两块连接板和倾斜缝的设置减小了局部应力，改善了结构受力状态。建立了防渗墙结构的受力模型，用于计算结构最大应力，检验结构安全性。
