摘要
位于露天采矿场边坡水龙山—杨桃坞的拦砂坝是一种轻型钢筋混凝土结构坝,考虑到采矿生产经常爆破产生的动力荷载对坝的作用,将坝简化为单自由度体系作结构动力分析,借助于辛普森公式对坝的动力反应进行数值计算,得出动力反应位移和弹性恢复力的近似基本参数,为该坝的结构设计和在正常使用阶段考察其耐久性提供了重要依据。
The dam located on an open-cut side slope in Shuilongshan-Yangtaowu, falls into a light-duty one in reinforced concrete structure for sand controlling. The paper, considering the dynamic loading impact resulted from the frequent mining blasting operation on the dam, simplifies the dam to one degree of freedom system for dynamic analysis. With the help of Simpson formula, the numerical value calculation of dynamics response of dam is made, educing basic parameters of dynamics displacement and elastic restorable force. The outcome lays an important foundation for structure design and durability investigating of dam structure in its normal service period.
