Comparación de los métodos topográficos aplicados en la construcción de túneles, utilizando el método convencional y la tecnología escáner láser 3D (ELT)

Abstract

Over time the science and technology work together to create or improve new machines and tools, ranging from a need for men to improve its performance, precision and efficiency. All known Sciences have evolved the way to carry their work in each of their fields, topography is not far behind, they have innovated new instruments of measurement and data collection, generating better accuracy, optimization of the work and new methodologies applied to each of the engineering activities; Additionally, these advances generated much more conformity and trust the engineer. Comparison of topographic methods applied in the construction of tunnels shows a step forward for now since using the new Terrestrial Laser Scanner 3D (TLS 3D) technology, we know that the presence of tunnels in a society is of utmost importance, as they are essential for the transport of long distance, development and innovation of regional economies. On the other hand, the TLS is a device that allows several applications in the construction industry, this instrument works with cutting edge technology, offering an infinite number of applications that are very significant. In addition, the laser system that handles the scanner is qualified like a solution that goes so far as to replace the photogrammetry, that is to say, this one allows to generate in detail digital models of the area MDT. The object of this work is of comparing the information obtained by the TLS with the employment of conventional topography in areas of difficult condition of work and access inside an underground work. The object of this work is of comparing the information obtained by the TLS with the employment of conventional topography in areas of difficult condition of work and access inside an underground work. To determine the efficiency of the TLS and topographic yields in terms of: accuracy, data, processes and profitability, the study area is located in the access tunnel to the hydroelectric power plant in Prado-Tolima.
