Method for determining irregular wave force of narrow-shoulder breakwater parapet of pavement accropodes

Abstract

The invention discloses a method for determining irregular wave force of a narrow-shoulder breakwater parapet of pavement accropodes, and belongs to a method for determining the irregular wave force of the narrow-shoulder breakwater parapet. The wave force is determined by values of a before-dyke relative water depth d1 / H1 percent and a wave level L / H1 percent which are acquired according to factors of breakwater cross section size, wave elements, tidal level and the like; and the wave force comprises 1 / 3 large-value horizontal wave force Fx 1 / 3, maximum wave pressure Pmax, a distribution function Y(x) of a wave pressure distribution curve on a side facing waves, horizontal-force wave action height h, 1 / 3 large-value uplift pressure Fy1 / 3, 1 percent cumulative frequency horizontal wave force Fx 1 percent and 1 percent cumulative frequency uplift pressure Fy 1 percent. The method can accurately and reasonably determine the irregular wave force of the narrow-shoulder breakwater parapet which uses pavement accropodes as protective face blocks, can make the design of the breakwater parapet safe and economic, has the advantages of accurate calculation, strong operability and the like, and is suitable for the calculation of the irregular wave force of various narrow-shoulder breakwater parapets which use the pavement accropodes as the protective face blocks.

Description

Technical field [0001] The invention relates to a method for determining the irregular wave force of a breast wall of a narrow-shoulder breakwater breakwater using a twisted king block body as a facing block, and belongs to the technical field of determining the wave force of the breast wall. Background technique [0002] The slope breakwater with the twisted king block surface protection is widely used in coastal engineering. The top of the dike is often set with a breast wall to reduce the elevation of the top without reducing the standard for resisting wave climbing. It can also be used as a gateway to berthing facilities, navigation facilities or inspections. And maintenance channels. Whether the design of the parapet wall is reasonable or not has an important impact on the safety and cost of the breakwater project. The stability design of the parapet must first determine the wave force, but the existing methods for determining the wave force of the parapet wall are not perfe...

Problems solved by technology

Whether the parapet design is reasonable or not has an important impact on the safety and cost of the breakwater project, and the stability design of the parapet must first determine the wave force, but the existing methods for determining the wave force of the parapet are not perfect, and the currently used pair uses the twisted king There are few systematic studies on the irregular wave force of breakwater breast wall with block armor, and its determination method is even more unreasonable. Only a fixed coefficient is used to reflect the influence of various types of blocks, and more is based on The design experience of engineering designers, this method is used in engineering design, and the calculation results often deviate greatly from the actual situation, which often leads to uneconomical and unsafe parapet design
