| 摘要: |
| 对某液化天然气(LNG)接收站取水结构采用1∶36.5比尺进行了多种水位(100年一遇高水位,50年一遇高水位,设计高水位,设计低水位和50年一遇低水位)与不规则波组合作用下的波浪物理模型试验.试验过程中测量了取水口戽头及第1节方涵的波压力,分析了取水量对波压力的影响以及不同水位条件下取水口戽头及第1节方涵波压力的变化规律.取水条件按照一期取水量(27 600 m3/h)、二期取水量(55 200 m3/h)与不取水3种工况考虑.试验结果表明,随着水位的降低,各点测得的波压力呈现出明显的增大趋势;不同取水量条件下,各点测得的波压力相差不大,最大相差幅度为5%～8%. |

| Abstract: |
| Wave tests of a water intake structure in a liquefied natural gas(LNG) receiving station are carried out under the conditions of different water levels and irregular waves.The model scale is 1:36.5.During the tests,wave pressures of the water intake bucket and the first quadrate culvert are measured.Some influences of water intake quantity and water level on the wave pressures are analyzed.The conditions of water intake quantity are the first phase quantity(27 600 m3/h),the second phase quantity(55 200 m3/h)and zero.The test results show that the measured wave pressures become larger with water level decreasing.For different quantities,the max difference of the wave pressures is from 5% to 8%. |
