| 摘 要： | 侧向进水条件下的前池水流将形成螺旋流和回流.实验丧明,影响螺旋流强度的主要因素是侧孔孔高与水深的比值;影响前池内侧回流长度的主要因素是引渠宽与前池宽的比值和侧边进口宽与前池宽的比值.在各种改善水流措施中加设导流墩和潜墩效果显著,可以使前池因测向进水引起的不良流态得到改善.

An Experimental Study on Flow Patterns in the Forebay with Side-intake |
| |
| Abstract: | In this paper presented are the results of an experimental study on the spiral flow and recirculation formed in the forebay with side-intake. The investigations show the main effect of the ratio of the height of the side-intake to the water depth on the strength of the spiral flow, and the main effect of the ratio of the width of the approach channel to that of the forebay and the ratio of the width of the side-intake to that of the forebay on the length of recirculation. Of the various schemes studied, the best one is to install the diversion piers, which can help to improve the flow pattern induced by the side-inflow in the forebay. |
