摘要
该文结合溪落渡水电站,采用先进的模拟方法和量测手段,对在高水头、大流量作用下,止水完全破坏、锚筋失效等极端条件下,反拱水垫塘单底板块的位移进行了详细的试验研究,得到板块位移沿程变化的规律及其时域特性和频域特性。研究表明,反拱底板由于拱的自锁作用使其保持稳定,稳定性明显优于平底板。
This article is an experimental research on the displacement of a single slab in the invert arch plunge pool under the extreme conditions of completely damaged watertight seal and invalidated anchor rod and under the impact of large discharge from high water head with advanced simulation and measurement methods with regard to Xiluodu Water Power Station. The displacement distribution laws for the vibrating slab along the flowing path and its time domain and frequency domain characteristics are obtained. The results show that the invert arch floor can keep its stability by the action of locked arch and its stability is superior to the flat floor.
