摘要
泉溪大桥于琼江、涪江交汇口以上约75 m处跨越琼江,桥位河段船舶通航条件复杂。文中建立了工程河段贴体正交坐标系下的平面二维水流数学模型,并利用该模型进行拟建大桥通航论证研究;分析了拟建泉溪大桥的通航净空要求及该河段的通航条件要求。
Quanxi Bridge spans Qiongjiang river upper the river mouth about 75m, where navigation conditions are complicated. Based on the site investigation a two-dimensional horizontal numerical mode in orthogonal body-fitted coordinate for flow was established to study the navigable dimension of Quanxi Bridge. The results of calculation showed that the bridge＇s navigable dimension is up to the mustard.
