This document describes the implementation of the foundation of technique, deep radial CPRconsolidation used in the construction of the new port in Itacoatiara city -AM. The method adopted is intended to treat the soil. This treatment is performed when the geomechanical characteristics are applied for carrying structures. Since the region is composed of original soil sandy sediment formations, sandy-silty and sandy clay of low cohesion, a phenomenon known as " Fallen Lands " Because of these

... tors, the soil presents little resistance to the action of causative agents of the phenomenon, such as the hydrodynamic pressure, hydrostatic pressure, structural and neotectonic factors, climatic factors, lithologic, and anthropogenic. The use of CPR aims to soil pore pressure dissipation making it stable. In order to reduce and neutralize the forces acting and increase the resistant forces. Specific objectives will be discussed the method in their steps detailing the geotechnical properties and procedures of instrumentation, showing that the applied technique is the solution for soil treatment in certain places applied to it, according to the polls.
