Economic Technical Feasibility of Modified Geopier RAP

“…This bearing capacity is mainly due to its side resistance and its value was about 6% of the bearing capacity for Continuous Flight Auger. It is convenient to report that a group of load tests on Mini-Rap, presented in an initial and ongoing research on this one, has presented, for similar conditions, bearing capacity much higher than that found by the application of the method of Lawton et al (1994), which was used in the design of the geotechnical admissible load. However, the major objective of this pile model is to generate a soil improvement, as previously discussed.…”

“…Firstly, the projects were chosen for a medium-sized construction that presented a low to medium level of competence in the first depths. These projects were developed to study the foundation of the most heavily loaded pillar, by designing its foundation by the following methods: Décourt and Quaresma (1978) [8] for the cases of Auger Piles, Continuous Flight Auger and Root Piles Monteiro (1997) [9]; based on Aoki and Veloso (1975) [10] for Pre-cast Concrete Piles; and Lawton et al (1994) [11] for Mini-RAP. After dimensioning, it was found out the average cost for those foundations and related the costs of each in order to verify the economic viability of the Mini-Rap pile.…”
