Abstract

The use of bamboo in Indonesia has a good prospect because it has some adventages in the mechanical properties, for instance high tensile and bending strengths. These properties show that bamboo could be used as an alternative material for pile foundation, and soil reinforcement especially as reinforcement in soft clay. Considering these conditions, it is necessary to have a study on interaction between bamboo and soil. The bamboo used in this research was gigantochloa apus and the sand type was coastal sand with uniform gradation (rounded grain). The tests carried out were direct shear test and load test. Load test was carried out in two dimensional model. Frictional resistance was obtained from the different value between the total resistance and the end resistance. The test was carried out ten times for each variation and then average value was calculated. The deformation of the soil particle under the pile was also observed during the test. The result of direct shear test show the interaction between sand and bamboo. The internal friction angles (□) obtained from the test was 37 ° for sand-sand . the friction angle for sand-bamboo (□) were 29° for sand-non internodes bamboo, 30° for sand-bamboo with varying position of internodes and 32° for sand-middle internodes bamboo. The result of load tests also show the same pattern. Soil deformation showed that particle morement due to the largest load occurred under the sample.The soil particle moved parallel to the oirection of loading for soil under the pile. At side wall of the pile the soil partide moved parallel to the direction of pile.
