斜拉倒虹吸跨径及桥型选择

Selection of Span and Type of Diagonal Tension Inverted Siphon

针对在又宽又深、冲刷严重、环境及气候恶劣的内陆河流上修建跨河输水建筑物存在许多技术难题，提出了多种可供选择的跨径和桥型，指出方案选定中着重考虑的因素，并作了深入细致的分析探讨。特别强调了结构的受力特征和抗风、抗冲刷能力及防洪安全。

Aiming at some technical problems of constructing water delivery structures which are across the wide and deep inland river with serious erosion riverbed and terrible environment and climate, several spans and types of diagonal tension inverted siphons are provided for selection. The main factors which must be considered in the scheme selection, are pointed out and analyzed in detail. The stressing characteristics of the structures, the abilities of erosion-resisting and wind-resisting, and safety of flood control are emphasized especially.[
