<p>In this document the behavior is simulated within the criterion of service limit states of deep excavation using the finite element method. The methodology of running thesis entitled: Analysis of deformation in open pit excavations in soft soils of Bogota is presented, and the results of an application example where that considers a deep open pit with a section type B Cut &amp; Cover. With the Hardening soil model the behavior of soft soils of the city of Bogota, and structural elements such as walls and slabs screens are simulated simulated props Plate type as elastic elements. For characterization of the soil and the elements of the excavation, information available from studies and designs for the first subway line, section IV, North Canton sector collected. The modeling is performed in 8 stages simulating the construction process and consequently the results show deflections wall and settlements in the surrounding buildings.</p>
