High arch dam toe area is the focus of reinforcement design.
高拱坝坝趾区域是加固设计的重点关注区域。
The results show that localization will firstly occur at dam heel and dam toe, but the final failure mode depends on the dam shape.
结果表明拱坝的局部化最先出现在下游坝踵和上游坝趾，但其最终破坏形态与坝体型有关。
The test results show that the apron can reduce back flow at the dam toe, and the piers can obviously diminish river bed scouring near the scour resistant wall.
试验结果表明：护坦减轻了下游纵向围堰左侧坝趾处的回流淘刷，隔流墩明显减轻了防冲墙附近河床的冲刷，确保了坝基和下游纵向围堰的安全。
The results show that the failure of dam foundation is caused mainly by the extension of dam heel crack and the expansion of shear-yield zone of the foundation rock near the dam toe.
结果表明，坝基的破坏主要表现为坝踵裂缝的延伸和坝趾附近基岩剪切屈服区的扩展。
Main contents and results are as follows:(1)To evaluate dam toe line is of vital importance in dam computer auxiliary design, however, its evaluation traditionally adopts graphic solution.
