Abstract

The objective of the study is projecting and calculation of shore protection structure of the water recreation facility in northern climatic conditions of Arkhangelsk city. In the course of study, three constructive solutions including anchored or non-anchored Larsen dowel wall were projected based on geotechnical conditions of Arkhangelsk. Geotechnical conditions include physico-mechanical and strength characteristics of soils, determined in accordance with the geological regulations. The calculation of bank protection structures was performed in PLAXIS 3D Foundation package by the finite element method. The study represents diagrams and graphics showing the deformations of bank protection structure. The result of the study is a solution chosen according to the reliability criterion. Recommendations and directions for the future research were proposed.

Highlights

Organized water recreation is a promising area of urban infrastructure in Arkhangelsk city
Calculation of the first constructive solution of shore protection structure begins with modeling of the identified geological conditions
Three constructive solutions of shore reinforcement structures for geotechnical conditions of Arkhangelsk based on Larsen dowel were suggested

Summary

Introduction

Organized water recreation is a promising area of urban infrastructure in Arkhangelsk city. Objects of organized water recreation include yacht clubs, moorings, slipways etc. Arkhangelsk is located in the mouth of the Northern Dvina at a distance of 30 km from the White Sea. Arkhangelsk refers to the Arctic zone of Russia; there are some challenges such as adverse engineering and geological conditions and rigorous climate. While projecting the objects of organized water recreation much attention should be given to the structural features of the berthing facilities. In Archangelsk the ground is formed by plastic and turgid moraine loams lying at a depth of 2-2.5 m from the surface. During the periods of spring snowmelt and heavy rains the groundwater level lies near the surface. In the basin of the Northern Dvina, erosion is very strong. The berthing facility should serve to strengthen the river bank
