Geo-monitoring of basement slab at Abu-Dhabi Plaza in Nur-Sultan City, Kazakhstan

Abstract

In modern architecture, there is an increased need to design constructions in conditions of dense development. It is important to implement a project without hitches. However, during the construction process, design flaws or environmental impacts can often arise in the end result. Therefore, proper design and monitoring allow taking preventive measures that helps to avoid overhaul of buildings in the future, which also affects to the cost of project, and sometimes-human casualties. During and after the construction of high-rise permanent structures often-unacceptable cracking can occur in the external walls and at the base slab of the basement. Respectively, groundwater starts to leak through the cracks of basement, compromising the serviceability and durability of the basement and rendering it unusable. The paper presents the use of fiber-optic sensor technologies geotechnical engineering. In this paper, it has been established the possibility of foundation monitoring system using fiber optic sensors during the construction process. The monitoring system includes a distributed fiber-optic voltage measurement system using a fiber-optic cable, which allows you to control deformations that occur on the surface of the plate. This study involves an investigation of the foundation system in a high-rise buildings and structures in Nur-Sultan city.
