Long-term Deformations of a Historical Church on the Anzer Island, White Sea

Abstract

Current study is aimed at determining the rate of the sand ground dislocations near the ultimately steep slope. The purpose of this work to determine the velocity of the sandy soils on flat ground on extremely steep to slope. In order to determine the rate, we conducted periodical measurements of the width of the tensile fractures in the load-bearing walls of the building constructed in 1830. Building of the object and its restoration in the current century have led to the imperfect structure of the building, lacking steel ties in the brick walls, which should have been installed at different levels, specifically under the floor and at the level of the vault abutment. The absence of ties has resulted in rupturing of examined building due to tensioning of the moving foundation. The errors of the constructors have transformed this building into an experimental object. The direction and the velocity of the ground movement have been determined. Our results suggest that tensioning of the foundation should be considered when designing the structure of the buildings constructed on the sandy layer near bents.
