In this paper, state of exploiting Bachimen Tidal Power Station is described.This station is located in the area where there is rich in tidal power energy but fack of coal and oil.Dam is sited in a narrow gorge, the seabed is rocky, the condation is characterized by using the prefabri-cated-cassion structure, which is towed to the site.lt is the first example of using this technique to construct tidal power station in China, that will provide experience for large tidal power station and conventional hydro-power... In this paper, state of exploiting Bachimen Tidal Power Station is described.This station is located in the area where there is rich in tidal power energy but fack of coal and oil.Dam is sited in a narrow gorge, the seabed is rocky, the condation is characterized by using the prefabri-cated-cassion structure, which is towed to the site.lt is the first example of using this technique to construct tidal power station in China, that will provide experience for large tidal power station and conventional hydro-power plants with small head. 本文叙述了八尺门潮汐电站的开发。该电站处于缺煤缺油而潮汐能源丰富的地区,其坝址位于峡谷处,海床为基岩。采用预制浮这沉箱结构,以无围堰施工。这是我国首例用该技术建设潮汐电站,将为我国大型潮汐电站和低水头常规水电站提供经验。 On the basis of practice of construction the problem of displacement in caisson foundation of medium and small-sized cloughs is discussed,and the corresponding effective controlling and adjusticy measures are put forward. 在施工实践的基础上,对中小型涵闸沉箱基础施工过程中出现的偏位问题进行研究,提出了有效的控制和调整的方法。 In this paper,an optimal design of reinforced concrete rectangular caisson is studied by combining the part optimization and the whole optimization technique .The object function is the minimization of total costs of the caisson ,and the design variables are the sizes of a variety of members and the reinforced bars in each member.In order to analyze the sensitivity,the analytic method is used.The computational results indicate the efficiency and feasibility ,and the program is stable and convergent. 采用分部优化与整体优化相结合的办法对矩形钢筋混凝土沉箱进行了结构优化没计以材料造价最低为目标函数,以沉箱各种构件断面尺寸及配筋为设计变量采用解析法求敏度计算结果表明,程序是高效的可行的,是稳定和收敛的
