配合滞洪水库初步设计，开展了６项数学、物理模型试验研究，如滞洪水库整体动床模型试验、退水问及下游河道动床模型试验、大宁一稻田水库入库闸水工模型试验、退水闸水工模型试验、老京周公路桥基础冲刷及防护工程试验、小清河分洪闸过流能力试验等，为滞洪水库初步设计提供了科学依据和大量技术参数。 With the initial design of the flood detention reservoir, carried out six mathematical and physical model test research, such as stagnant flood reservoir overall dynamic bed model test, backwater asked and the downstream channel dynamic bed model test, Daning a paddy reservoir hydraulic engineering model test, Backwater sluice hydraulic model test, the old Beijing Jing Zhou Road Bridge Foundation Scouring and Protection Engineering Test, Xiaoqing River floodgate gate flow capacity test, etc., for the preliminary design of the flood detention reservoir provides a scientific basis and a large number of technical parameters.
