style="text-indent:25px">設(shè)計(jì)中，交通組織功能也要擺在重要的地位上，尤其是立交橋，不光橋上有車輛，橋下車輛也川流不息。如果不綜合考慮交通功能，下行車輛撞擊橋墩或有關(guān)橋梁部分，導(dǎo)致橋梁坍塌，這種事件在國內(nèi)外都有發(fā)生。作為橋梁設(shè)計(jì)人員必須注意這一點(diǎn)來進(jìn)行橋梁方案比選，乃至方案確定后的橋梁分跨。在貴陽市都司路高架橋跨越中華路的大南門交叉口位置，設(shè)計(jì)者在地面設(shè)置了交通導(dǎo)流環(huán)島，一跨20米跨徑的橋梁正好處于環(huán)島內(nèi)。橋梁建成后，隨著城市的發(fā)展，車輛的增多，該交叉口經(jīng)常塞車，不得已取消了地面環(huán)島。由于該交叉口的橋梁跨徑較小，導(dǎo)致左轉(zhuǎn)車輛的行車軌跡不順暢，司機(jī)抱怨連天，這無疑是橋梁設(shè)計(jì)敗筆。
