Numerical Analysis to Improve Soil Strength Using Bamboo Pile

Abstract

Soil reinforcement methods that is being developed recently. Considering into account the cost of relatively expensive, it is very necessary to try other alternatives that are cheaper and easily available around the construction site, for example the use of a bamboo pile as a soil reinforcement. Bamboo Atter is one kind of plant that grows abundantly in Indonesia and bamboo are very easy to obtain, and the price was relatively cheap. Bamboo does not require a long time to grow and produce great tensile strength. Tensile strength and compressive strength was higher than the bamboo wood is a material that is quite popular in the world of construction. Model testing is made of a steel drum tubes 60cm diameter with a height of 45cm ground soil. The soil very soft clay with high plasticity and swelling index. Tested by loading cell without bamboo reinforcement to know the dimensions of the ground failure at the beginning known reach 1,91mm. Pile bamboo made on actual diameter with varying heights of 10, 20 and 30cm and instilled in the soil models vertically. The results showed settlement can be reduced up to 70% on 5kN load.
