汉江王甫洲水利枢纽泄水闸护坦修建在地质条件较复杂的软岩地基上。护坦设计除充分利用覆盖层的透水性,采用防排结合的方式,充分削减护坦下的渗透压力外,主要利用锚桩提高护坦的抗浮能力,大大减少了护坦板厚度,不仅降低了工程造价,而且避免了泄水闸基础下游出现临空面。在软岩中设置锚桩以提高消能工的稳定性,在水利枢纽工程中尚不多见。 Han River Wangfuzhou Dam Sluice dam protection built on the more complex geological conditions of soft rock foundation. In addition to make full use of the cover design of the water permeability of the coating, the combination of anti-Pai way to fully reduce the infiltration pressure under the protection tank, the main use of anchor to enhance anti-floating shield capacity, greatly reducing the thickness of the tampon, not only Reduce construction costs, but also to avoid the spillway downstream Pro face area. Setting up anchor pile in soft rock to improve the stability of dissipator can not be seen in the hydraulic project.
