一、资料码头前方为两座独立的靠船墩,因码头位于回流区,故两墩以艏墩与(?)墩区别之,艏墩在长江主流向之下游。后方为钢筋混凝土引桥,与艏墩相接。码头于1965年建成投产,因墩的下部为直桩支承,在起重机运转或皮带机运行时产生振动。1969年实测了一次振动,方法 First, there are two independent pier piers in front of the data terminal. Because the pier is located in the recirculation zone, the two piers are separated from the pier by ()) pier and 艏 pier by the mainstream downstream of the Yangtze River. The rear is a reinforced concrete approach bridge, connected with the pier. The terminal was put into operation in 1965, because the lower part of the pier is a straight pile bearing, which generates vibration when the crane is running or the belt conveyor is running. 1969 measured a vibration, method
