Abstract

The article explores reinforced soil walls, focusing on the use of different reinforcement types and facings, and introduces a novel method for inspecting geometric changes using 3D laser scanning. This method, rarely applied to reinforced soil retaining walls, allows for precise monitoring of wall deformations, which is crucial for ensuring structural safety. The author discusses potential risks associated with exceeding deformation limits and highlights how laser scanning can support safety analysis. Real-life examples show how this technology captures geometry and geometric changes during both construction and operation, offering detailed measurements and facilitating ongoing maintenance. The article emphasizes the growing need for advanced technologies in the construction industry, particularly for large surface area structures like reinforced soil walls. It also addresses challenges in displacement estimation during the design phase and monitoring during construction and operational stages. The insights provided are valuable for all stakeholders in the investment process, including designers, contractors, supervisors, and infrastructure managers.
