Experimental studies of the stability of wave-damping slopes to protect bridge supports from wave action

Abstract

This article presents the results of experimental studies of the stability of wave-damping slopes to protect bridge supports from wave action. The object of the study is the construction of protective wave-damping slopes constructed to protect the supports of bridges designed and operated under wave action conditions (such as the bridge to Russian Island in Vladivostok, etc.) on the shores of the seas. The purpose of the work is to select the optimal design solutions for protective slopes that ensure reliable and safe operation of the bridge crossing during sea storms of rare frequency. The research was carried out by the method of physical modeling in a wave pool. Various variants of structural solutions of protective slopes are considered: from a stone outline and from gabions, as well as combined structures. According to the results of research on a physical model in the wave basin, the structures of the protective slopes of bridge supports that are most resistant to the effects of sea storm waves of rare frequency have been obtained. The results of the research are intended to select optimal design solutions for protecting bridge supports from wave action and can also be used to protect other transport structures, for example, the roadbed of railways designed on sea coasts. These results were used by the author in the development of the regulatory framework for the design and monitoring of engineering structures for the protection of transport structures from wave action.
