摘要
分析了目前国内所采用的抛石防护方法和土工织布上加压载防护方法的优缺点,对桥墩冲刷的机理进行了阐述,并且通过模型试验,研究了在桥墩周围抛投四面体透水框架进行防护的防护效果。从而证明了“四面体透水框架抛投防护方法”对桥墩局部冲刷的防护有一定的工程使用价值。
The merits and shortcomings of the protection method adapted now in China for the scour at piers are analyzed. The principle of the local scour at piers is described here. By a series of experiments, the effect of tetrahedron frame protection method (TFPM) is studied. Furthermore, it proves that the TFPM has some engineering value for protecting local scour at piers.
