Abstract:
Bamboo is used as reinforcement in soil mainly to stabilize slopes or river banks or to support roads. Now a days treated and untreated bamboo is used along with other materials such as bitumen, geotextile etc. in soft soil reinforcement. The present study attempts to review the behaviour of bamboo reinforcing elements under different loading conditions as well as in different structures.
In embankments sulphur treated bamboo mats have higher stresses and swelling potential under seismic loading. The foundation settlement of bamboo mats placed on mud deposit of break waters in Selangor, Malaysia indicated the maximum total settlement was limited to 15 cm in 2 years. No differential settlement was there in break waters which shows the integrity of the foundation mats. Laterite soil reinforced with bamboo plates placed in different layers subjected to various tests gives that the dry density of the molded specimens decreases with number of bamboo specimens. The Unconfined compressive strength and Modulus of rigidity increased with number of specimens. Case studies in Kualalumpur and Kuching in Malaysia reveal that the bamboo mattresses along with nonwoven needle punched geotextiles increases the bearing capacity of soft sub grade and also serves as a good separator. A detailed review of the bamboo reinforced soil has been carried out.
