【摘要】 以密云水库第二溢洪道弧门改建工程为背景,对弧门的设计方案运用两种方法分别进行了静力应力分析,一种为规范规定的对水平∏形框架结构计算的平面体系方法,另一种为空间体系的有限单元法。对两种方法计算结果进行了分析对比,得出重力和空间效应对弧门应力情况有较大的影响,对弧门的设计和管理有一定的参考价值。更多还原

【Abstract】 Based on the background of the rehabilitated project of the radial gate for No.2 spillway of Miyun reservoir, the static force analysis is made for a design of the radial gate with two methods, Which one is standard structure mechanics method for horizontal Π-shaped structure and the other is FEM method. Through comparison of computation results from such two methods, the influence of gravity and space effect is notable for radial gate, which has certain value for reference to the design and management of radial gate.更多还原
