乌锡铁路黄河特大桥地处桥址位于黄河三湖河口至昭君坟段,北岸为乌拉山山前倾平原,南岸为鄂尔多斯台地,桥址地下水位15m是振动液化层,液化层深度为2～15m,地质条件差、成孔难度大、钻孔深度深是施工面临的主要难题,通过对钻机的选型、钻进速度的控制、钢护筒的埋设、泥浆密度的调整,解决了振动液化层桩基钻孔施工难题,取得了一定的经验。 Wu Xi Railway Yellow River Bridge is located in the bridge located in the mouth of the Yellow River Lake mouth to Zhaowun grave section, the north shore of Wulashan Hill before the plain, south bank of the Ordos platform, bridge site groundwater level is 15m vibration liquefied layer, liquefied layer depth of 2 ~ 15m, poor geological conditions, difficult hole formation, deep drilling depth is the construction of the main problems facing the drilling rig selection, drilling speed control, buried steel tube, mud density adjustment to solve the vibration liquefaction Layers pile drilling construction problems, and made some experience.
