SAFETY EVALUATION AND DYNAMIC COUPLING ANALYSIS OF COUNTER-ARCHED SLAB IN PLUNGE POOL

摘要：

The stability of plunge pool slab of hydropower station is crucial to energy dissipation, but the working conditions of counter-arched slab is very complex and its stress procedure is considerably nonlinear and coupling. Therefore, a nonlinear dynamic coupling method to analysis the counter-arched slab configuration is put forward, which can reflect the coupling of dynamic loads, slab, anchor bars, groundwork and abutment as well as the dynamic procedure of instability. Various nonlinear factors and static-dynamic coupling are taken into consideration, and the working conditions, stress mechanism, dynamic instability procedure and influential instability factors are revealed. The proposed method thus provides a more comprehensive safety evaluation method of plunge pool, which further provides an important theoretical basis for engineering design of counter-arched slab in plunge pool.
