Breakwater with self energy dissipation effect

Abstract

The invention discloses a breakwater with a self energy dissipation effect. The breakwater comprises a water retaining dike and a flow guide dike, wherein the water retaining dike is fixed on a bank slope; the flow guide dike is arranged on a wave facing surface of the water retaining dike and is fixed on the top of the water retaining dike; the inner side outer wall of the flow guide dike is matched with the shape of the wave facing surface of the flow guide dike; in addition, the inner side outer wall of the flow guide dike is in contact with the wave facing surface of the water retaining dike; the outer side outer wall of the flow guide dike extends to the water body range; an inwards recessed circular arc flow guide surface is arranged in the lower part of the flow guide dike; smooth transition is realized between the inner side end part of the circular arc flow guide surface and the wave facing surface of the water retaining dike; and the wave facing surface of the water retainingdike and the circular arc flow guide surface inside the flow guide dike jointly form an annular flow passage, so that waves spread to the bank slope climb along the wave facing surface of the water retaining dike, enter the annular flow passage, and form a rotary fluid capable of realizing self energy dissipation along the annular flow passage. The breakwater structure avoids a wave overtopping phenomenon of the waves, realizes the self energy dissipation effect of the waves, and can realize a landscape function.

Description

technical field [0001] The invention relates to the fields of port and nearshore engineering and landscape, in particular to a breakwater capable of realizing self-dissipation. Background technique [0002] Port and nearshore engineering is a hot field in recent years, which involves various fields such as water conservancy and transportation, and has huge social public service capabilities. In port and nearshore engineering, breakwater is the most common port construction. Its function is to defend against wave intrusion. It is generally located on the periphery of port waters and has the function of preventing the invasion of drifting sand and ice. Breakwaters can be divided into three types according to the section form: slope type, straight wall type and mixed type. [0003] Due to the uncertainty of the wind and waves on the sea surface, there will often be unpredictable strong winds and waves. Although the design of the breakwater has considered certain anti-wind and...

Problems solved by technology

The over-wave phenomenon will have a serious impact on the bearing capacity and stability of the breakwater. If the number of over-wave occurrences increases, it will easily cause the breakwater to fail and damage other port structures.
