力洋港大桥桥面行车风环境风洞试验研究

Study on Wind Tunnel Test of Deck Driving Wind Environment for Liyang Harbor Bridge

通过风洞试验研究了在设置防撞栏和风障两种情况下力洋港大桥桥面风速分布情况。试验结果表明,在设置了风障后,消除了桥面2~4.5 m高度范围内桥面高风速区,有效降低了桥面侧向风速,使得大桥桥面具有了比其接线高速公路更为优良的侧风行车安全性。

According to the wind tunnel test, the article studies the deck wind speed distribution of Liyang Harbor Bridge under two conditions of installing the crash barrier and windbreak. The test result shows that the deck high wind speed zone within the 2~4.5 m height range of deck is eliminated after the windbreak is installed, which efficiently reduces the lateral wind speed of deck and makes the bridge deck have the more excellent crosswind driving safety than connected with the expressway.
