淤地坝是黄土高原丘陵沟壑区拦泥减沙、建造高产农田的主要工程措施。但近年来洪水垮坝的调查表明,有不少淤地坝由于溢洪道设计不合理而导致坝体破坏或垮坝,严重影响其利用效果。因此,合理设计溢洪道是确保淤地坝安全利用的关键。现代微计算机的普遍应用,为淤地坝设计提供了一个方便的计算工具,编制一种能进行多种 Warping dams are the main engineering measures for sediment reduction and sedimentation in the hilly and gully regions of the Loess Plateau and for the construction of high yield farmland. However, the investigation of flood collapse in recent years shows that many of the silt dam have caused dam damage or collapse due to unreasonable spillway design, seriously affecting the utilization effect. Therefore, the rational design of spillway is the key to ensure the safe utilization of silt dam. The universal application of modern microcomputer provides a convenient calculation tool for siltation dam design,
