一、试验概述(一)试验目的和要求鲇鱼湾油码头的墩柱采用大型圆沉箱结构,这种沉箱尺度大(直径9米、高19.7米)、自重大(不计盖板自重为772 T)、形状特殊(底部带八角的悬趾),浇注地点(大连港三码头)距现场远((17浬)、,拖运时受风浪及航道水深限制,特别是后者,决定了该型沉箱不能采用一般的压水至稳定立拖的方法.为保证在倾复及拖运过程中的安全和稳定,为寻求安全合理的施工方案,根据鲇鱼湾建港指挥部的委托,由交通部第一航务工程局第三工程处和大连工学院水利系合作,于1976年6月进行该项试验。
First, the test overview (A) the purpose and requirements of the experiment Bondington oil pier piers using large circular caissons structure, the Caissan scale (9 meters in diameter, 19.7 meters high), self-weight (excluding the weight of the cover 772 T ), Special shape (bottom with octagonal hanging toe), pouring site (Dalian Port three wharfs) far away from the scene ((17 浬), towing by wind waves and channel water depth constraints, especially the latter, determines the type Caissons can not be used to stabilize vertical pressure watering method.In order to ensure the safety and stability during the dumping and towing process, in order to seek a safe and reasonable construction program, according to the entrustment of the Port-au-fish Bay Command, The Third Engineering Department of the First Flight Engineering Bureau cooperated with the Department of Water Resources of Dalian Institute of Technology and conducted the test in June 1976.
