桥头引道的路堤处在极其不利的条件下工作着,在洪水期它周期性地淹没在滩堤产生的波浪中,从桥位上游下来的流水对桥梁的附近也是特别有害的。由于洪水产生的不利作用而防护河滩路堤的边坡——这是引道设计中最重要的一个细节,在桥头引道设计的实践中获得最普遍采用的是装配式钢筋混凝土板,或者整体式混凝土的平面板永久型式的加固,这种加固 The embankment of the bridge approach works under extremely unfavorable conditions, during which it cyclically floats in waves generated by beach banks, and the water flowing down the bridge is also particularly detrimental to the vicinity of the bridge. The side slope protecting the beach embankment due to the detrimental effects of flooding - the most important detail in the approach design - the most commonly used in the practice of bridgehead design is the fabricated RC slab, or the monolithic The permanent type of concrete flat panel reinforcement, this reinforcement
