摘要
本文对土石坝的溃坝模式进行了简述,针对土石坝漫顶溃坝模拟分析的概化数学模型编制了计算程序,并结合大洼水库溃坝的工程实例进行数值模拟,与该工程实例的实测数据进行了比较分析,进一步说明土石坝漫坝计算过程中数学模型与假设对计算结果、精度、风险分析的重要性。
In the paper,dam failure mode of earth-rock dam is introduced briefly. Computing procedure is formulated aiming at the generalization mathematical model of earth-rock dam overtopping failure simulation analysis. In addition,the engineering example of Dawa Reservoir dam failure is combined for numerical simulation. The data is comparatively analyzed with measured data in the engineering example. The importance of mathematical models and assumptions on calculation results,precision and risk analysis in the process of earth-rock dam overtopping calculation is further described.
