Abstract

Infrastructural development faces the dilemma of attempting to construct over deep soft ground. Practical methods to support heavy engineering construction over soft ground has evolved tremendously. Proper ways to treat a depth of softness that extends to a great depth technique are pretty expensive and non-functional. Furthermore, those available methods have their practical limitation during implementation. Bamboo Geotextile System “GEOBAMTILE” is designed to solve a critical contemporary civil engineering problem of supporting hefty construction safely over deep soft subgrade without attracting excessive settlements in due course. This study aims to evaluate the performance of Geobamtile on settlement reduction. Methodology to achieve the objective of the study is by data collection from the site. The next phase continues with construction of road work and analysing the result collected. Based on this study, it is found out that the implementation of Geobamtile reducing the settlement rate of foundation effectively. Compared to the predicted settlement design, the field data result is 88mm to 100mm compare the predicted settlement for the first 100 days is 301mm to 341mm. Soil settlement reaches a relatively constant value despite an increase in backfill height. From this study it shows that Bamboo Geotextile System “Geobamtile” is effective for heavy construction over deep soft ground compare to the predicted settlement design.
