| 摘 要： | 讨论了水工建筑物上脉动压力的合成问题。指出脉动压力的合成要充分考虑到各点压强的时空相关 ,并由相关尺度给出了作用于建筑物上脉动压力的总荷重及用拟静力法分析结构时的分布荷重 ,对于脉动总荷重而言 ,相关尺度是一个与作用面积和压强有同等意义的重要参数。

| Abstract: | The resultant of the fluctuation pressure on the hydraulic structures is discussed. It is thought that the time-space correlation between the pressures on every point should be considered sufficiently in calculating the resultant of the fluctuation pressure. Both the load of the fluctuation pressure on the whole surface of the structure and the distribution of the pressure for the similar-static structural analysis are derived from correlation scale. It is shown that for the summary fluctuation pressure on the surface of the construction,the correlation scale is a parameter as important as the pressure intensity and the functional area. |
