浅谈对特殊涵闸结构形式的安全计算分析

Safety Analysis for Sluice Gate with Special Structure

以西江某穿堤涵闸为例,采用地层结构法和结构荷载法对混凝土和浆砌石结合形式的穿堤涵闸结构进行内力分析计算。计算结果表明,拱顶混凝土抗拉强度不满足设计要求,现场涵身裂缝位置和发展趋势与计算较吻合。计算结果可作为涵闸安全评价的技术支撑依据之一。

The Layer structure method and load structure method are applied to analyze the internal force of the structure of a sluice gate in Xijiang River,which is constructed by concrete and stone masonry. The results indicate that the tensile strength of the concrete at the top of arch cannot match design requirement,and the real position and developing tendency of cracks on the sluice gate is well predicted by the calculation. The method applied in this paper is capable of being one of the technical references for safety evaluation of sluice gate.
