2nd Seminar on Transportation Geotechnics, Soil Improvement Challenges on Alluvial Zones

Abstract

The aim of this abstract is to present the main design and execution criteria related with ground improvement solutions, using jet grouting columns as foundation and cofferdam solutions, at the MYRIAD SANA HOTEL , located next to the Vasco da Gama Tower, at the Tagus river right bank, in Lisbon, Portugal. The hotel , with two underwater floors and twenty two upper floors, is located at the river, over alluvial soils with a thickness of about 17m, resting over Miocene soils. This complex scenario demanded the use of some unusual ground improvement solutions, related and interconnected with foundation and cofferdam solutions. The main results of the adopted finite element models are presented, as well as of the monitoring and survey plan.
