| 概要 |
With a view to facilitating the determination of the pressure line within the section of a debris dam, charts have been prepared which give the position of the pressure line in the base and top as wel...l as in the joints through the points dividing the height of the dam into six equal parts. The distance of the point where the line cuts a horizontal section from the centre of the section is expressed in terms of the upstream batter and the respective ratios of the spillway width and overflow depth to the depth of the section below the spillway, the downstream batter being assumed 0.2:1 and the specific weight of the masonry twice that of the overflowing water.続きを見る
