橡胶坝塌坝产生的最大泄流量是汛期橡胶坝控制运用的关键,为了快速准确地计算橡胶坝塌坝产生的最大泄流量,依据橡胶坝坝高、河道比降、蓄水量、坝长及塌坝时间等因素组合了102个塌坝方案,模拟计算了塌坝产生的最大泄流量。分析表明,橡胶坝塌坝产生的最大泄流量与坝长、蓄水量、河道坡度、坝高、塌坝时间等因素有关。在此基础上,利用统计分析方法建立了橡胶坝塌坝产生的最大泄流量估算经验公式,该公式包括了蓄水量、塌坝时间、坝长、坝高、侧收缩系数等因素。经验证该公式具有快速、准确的特点,方便实用。
Abstract
The maximum discharge generated by the collapse of rubber dam is crucial for the control and running of rubber dam in flood season. To calculate the maximum discharge caused by rubber dam collapse quickly and accurately, 102 scenarios of rubber dam collapse were designed to simulate the maximum discharge caused by dam collapse. Dam height, river slope, water storage, length of dam, and dam collapse duration and other factors were selected as variables in the scenarios. The empirical formula for estimating the maximum discharge generated by the collapse of rubber dam involving dam length, dam height, water storage, complete dam collapse duration, and lateral contraction coefficient was presented using statistical analysis method. Example verification demonstrate that the empirical formula is quick in calculating and accurate in result, and also practical and convenient.
