为使自身不稳定的沉箱,在吃水受到施工条件限制时采用起重船吊扶安全出运,必须对其稳定性进行计算,必要时应进行模型试验。这是沉箱重力式结构物设计、施工中不时碰到的问题。自身不稳定的沉箱在起重船吊扶出运时,如何计算,看法不一,也有争论。耿茂东工程师提出了他的看法,现予刊出,欢迎对本文提出意见并展开讨论。 In order to make its own unstable caissons, when the draft is restricted by the construction conditions, the lifting vessel shall be used for safety shipment and the stability of the caissons must be calculated. If necessary, model tests shall be carried out. This is the caisson gravity structure design, construction from time to time encountered problems. How to calculate and disagree with the unstable caissons in the lifting of crane lifts and frets also argues. Geng Mao-Dong engineer put forward his opinion, is now published, welcome to this article for comments and discussions.
