Caracterización del subsuelo a través de métodos geotécnicos y geofísicos en la Urbanización Valle del Espíritu Santo. (Pamplona, Norte de Santander).

Abstract

This work shows the use of geophysical and geotechnical to characterize the surface shallow in the Valle del Espiritu Santo urbanization in Pamplona, department of north of Santander, (Colombia). The techniques implemented are; Seismic Refraction Tomography (SRT), Multichannel Analysis of Surface waves, (MASW). Vertical Electric Sounding (VES); and the Standard Penetration Test (SPT) for the geotechnical case. The main objective of this work was to obtain some physical properties of the soils in the area of interest, and give an explanation about the possible causes of the structural and pathological faults. The data were recorded by surveying four seismic lines seven SEV and one SPT; In this context, the document presents the results of a data integration where three layers: the first layer with between Vp 300-1228 m/s, Vs of 121-335 m/s, thickness of 3.13 a 6.3m and resistivity of 30.7-130 Ωm, which corresponds to clay loam. While the second layer has Vp values ranging from 997 to 1706 m/s, white wave speeds S of 264481 m/s, thickness between 6.3 to 20.4 m and resistivity of 6.19-258 Ωm, said layer is classified

as clayey sand. Layer number three presents Vp between 1281-1829 m/s, Vs of 380 to 601 m/s.

The admissible

load capacity of the ground is 460.61 Kpa, where we can conclude that the soil must be stabilized to carry out any type of construction.
