Inverted arch plunge pool arch block instability limit load analysis method
The invention discloses an anti-arch plunge pool arch block instability limit load analysis method, which comprises the following steps of: establishing an arch block instability mechanical model through a structural mechanics method, and dividing the arch block instability process into three stages of middle arch block lifting, two-side arch block sliding and two-side arch block tilting. The model is simplified under the condition of considering engineering safety and reasonable calculation complexity, and the simplified structural mechanical analysis method convenient for manual calculation is provided. According to the method, the buckling limit loads of the arch blocks corresponding to different anchoring forces of the inverted-arch plunge pool can be calculated, a reliable theoretical basis is provided for structural design of the inverted-arch plunge pool, and the method has good engineering application value.
本发明公开了一种反拱水垫塘拱块失稳极限荷载分析方法，通过结构力学方法，建立了拱块失稳的力学模型，将拱块失稳的过程总体分为中间拱块抬起、两侧拱块滑动、两侧拱块翘起三个阶段。在考虑工程安全且计算复杂度合理的情况下简化模型，提出一种便于手动计算的简化结构力学分析方法。本发明的方法可计算反拱水垫塘不同锚固力对应拱块失稳极限荷载，为反拱水垫塘结构设计提供了可靠的理论基础，具有较好的工程应用价值。
