Georgian Scientists/ . 7 N 2, 2025 510 Selection of protective structural systems for new construction in densely populated areas Beka Gurgenidze Georgian Technical University Abstract Georgia has a diverse relief and complex geological conditions, high seismic activity, frequent mudflows and landslides. In these conditions, it is necessary to use technologies that ensure both economic efficiency and the stability and safety of engineering structures. Particularly noteworthy is the densely populated urban environment, where ensuring safety and stability is associated with many difficulties and costs: the process of installing sheet piles is accompanied by high levels of noise and vibration, limited working area, specific conditions of a particular construction environment, etc., which requires additional work and, of course, increased costs. For the last 10 years in Georgia, the technology of screw mounting has been intensively implemented. Pile pile is a metal sheet that, when driven into the ground, forms a kind of iron curtain that performs the function of a protective barrier and is used in the construction of temporary and permanent structures. Sections provide maximum strength at minimum costs. The construction of connecting beams allows you to fasten them with clamps or bury them, creating a solid wall consisting of connected sections. However, it should be noted that there are many obstacles: insufficient development of theoretical and practical studies, implementation of international standards, which significantly complicates the wider implementation of technology and its development. Despite these disadvantages, Larsen piles are used both in temporary and permanent structures: in the retaining walls of pits, in strengthening the banks of rivers, in the construction of ports, in the construction of roads and bridges, and especially in the implementation of safe construction works in historical and densely populated
