白莲河水库第二溢洪道为二级消能，由泄槽和出水渠组成。
The second spillway of Bailian River Reservoir is of two-level energy dissipation, which is composed by discharge flume and outlet canal.
出泄槽水流挑流消能后在渠道内加速，使出渠流速仍然较高。
The water flow in the canal speeds up after energy dissipation in the discharge flume, so the velocity of flow is still high in the canal.
在许多试验研究的基础上，提出了台阶式泄槽溢洪道泄槽及降低护坦式消力池的水力计算方法。
Based on extensive experimental studies, hydraulic computation methods are put forward for the design of the stepped discharge chute and the stilling basin formed by lowering apron.
