CONGRESO Dynamic compaction evaluation using in situ test


ABSTRACT Land reclamation often involves the placement of loose granular soil (gravel/sand) by means of hydraulic filling. These soils generally have a low relative density, under static loads, loose granular soil may be subjected to bearing failure and large settlements. Various densification methods of deep compactacion (dynamic compaction, vibroflotation, stone columns, etc.), but for large areas, usually the most economical method is the dynamic compaction. This method improves, need a process control. The ¿in situ¿ techniques selected to control the improvement grade were: boreholes with SPT tests, DPSH, CPTU, CSWS geophysical tests, SEISMOGRAPH monitoring and topographic control of settlements. These in situ techniques allowed to evaluate the dynamic compaction efficiency as well as the ground modifications that could cause potential damages to adjacent buildings (in case we have some gas tanks).
