ASSESSMENTS OF GEOSYNTHETIC PERFORMANCES FOR IMPROVEMENT OF SOFT FOUNDATION SOILS IN COASTAL AREAS

摘要

Theoretical studies have been performed for drainage and filtration characteristics, low consolidation rate of sand mat and prefabricated horizontal and vertical drains. These prefabricated horizontal drains were adopted to substitute for sand mat in domestic highway construction sites and test instrumentation was installed to investigate the drainage and filtration capacities of these materials. Finally, discussion on quality control and methodology is presented.
