【摘要】 在山东菏泽发电厂三期工程煤场与主厂区被一条市政主干道隔开,市规划部门不允许在道路中间增设支柱,使该栈桥跨度达到55m.这大大超过常规栈桥跨度,在国内火力发电厂也较为少见.文章介绍该栈桥的竖向地震和温度应力计算,为以后的超长栈桥设计提供借鉴.更多还原

【Abstract】 Based on a practical engineering of the Third Phase Project of Shandong Heze Power Plant,the vertical seism and temperature calculation of super-large span coal handling trestle is described.In the project of Heze Power Plant area,there is a main municipal road between the coal yard and the main power-house area,which makes the span length of the trestle reached 55m.It is much longer than normal trestle and rarely to see in China.In this paper,the structure form of the trestle for Heze Power Plant,and vertical seismic analysis and vetical thermal stress analysis results are given so as to provide reference for the design of other super-large span coal handing trestles.更多还原
