本文描述了东亨廷顿桥施工的各个方面。这是一座600m长的预应力混凝土斜拉桥。斜拉部分的主梁采用节段拼装法施工,每段重227t用长线法在工地以外镶合浇注,由驳船运到桥位,再用544t浮吊起吊就位。南引桥采用就地悬臂浇注法施工。结构的预制部分与就地浇注部分均采用高强混凝土,其规定的28天抗压强度为55MPa。
This article describes various aspects of East Huntington Bridge construction. This is a 600m long prestressed concrete cable-stayed bridge. The main part of the cable-stayed part is constructed by segmental assembling method. Each section weighs 227t and is cast in place by the long-line method outside the construction site. It is transported to the bridge by the barge, and then lifted by 544t floating crane. South Approach Bridge using local cantilever casting method. Prefabricated part of the structure and cast-in place are made of high-strength concrete, the provisions of the 28-day compressive strength of 55MPa.
