| 摘 要： | 根据桥位选择的基本原则，结合桥区工程概况、航道条件等方面对正交及斜交2个桥位进行比较，得出景洪勐泐大桥斜交桥位为推荐桥位。通过对斜交桥位各桥型方案的通航净空尺度、桥墩位布置等因素对通航影响等方面进行研究，确定将330 m跨钢箱拱桥桥型作为推荐桥型。最后通过水流数值模拟并结合实测资料进行分析，分析建桥后对通航水流条件的影响情况, 从而更加确定推荐方案的合理性。

| Abstract: | According to the basic principles of the bridge site selection, and combining with the bridge area project overview and channel condition, we compare the orthogonal and bias bridge sites, and draw the Jinghong Mengle bridge skew bridge site as the recommended bridge site. Based on the research on theinfluence of navigation clearance dimensions and pier bit arrangement on navigation, we determine the 330 m span steel box arch bridge as the recommended bridge. Moreover, through the flow numerical simulation and combining with the measured data, we analyze its influence on navigation flow condition and thus determine the reasonableness of the recommended scheme. |
