摘要
该文对能量法计算江河水面线中的特殊地形对计算成果的影响、糙率误差对成果精度的影响、局部水头损失系数的合理选取、水面线推算方向的选择、起算水位的"消噪"处理、计算方法等常见问题进行了初步探讨,可供水利设计同行参考。
A preliminal7 study has been conducted in this paper on several common issues in the calculation of river water surface line by energy method, namely the influence of special topography on the outcome of computing, the effect of roughness errors on ac- curacy of results, reasonable selection of local head loss coefficient and the direction of water surface line projections, " noise can- cellation " of the starting water level and calculation methods, aiming to provide some references to water engineering design peers.
