一前言圆筒形泵房设计,惯用的方法是以抗浮稳定作为结构物的主要控制条件.要求泵房底板以上的总重量(包括一定的机电设备)G,能克服浮力W,而不致浮起.对于直径较大,洪水位高的圆筒形泵房,往往很难满足这一基本要求,有时为了满足抗浮,迫使筒壁和底板加得很厚,工程量十分可观,表1列举广西六十年代在左江,郁江上的几个泵房,根据上述要求设计的工程特性. I. INTRODUCTION The design method of cylindrical pump house is based on the anti-floating stability as the main control condition of the structure, requiring the total weight above the pump room floor (including certain mechanical and electrical equipment) G to overcome buoyancy W without floating For large diameter, high water level cylindrical pump room, it is often difficult to meet this basic requirement, and sometimes in order to meet the anti-floating, forcing the cylinder wall and the floor plus very thick, the project is very impressive, Table 1 lists In the sixties of Guangxi in the left river, Yujiang several pump room, according to the above requirements of the design characteristics.
