ANALYSIS OF FOOTINGS ON VESICULAR LATERITE

A finite element programme was developed for the analysis of footings on vesicular laterite incorporating the strength and stress-strain laws arrived at by performing drained triaxial tests on undisturbed samples of the laterite. Footings of different diameters were analysed by the method. A number of plate load tests were carried out to compare the results. The agreement is good. The load-settlement curves show the influence of cementation at lower loads and crushing of the material at higher loads. The conventional method of bearing capacity analysis is not applicable to laterites. The limiting load carrying capacity is mainly controlled by settlement considerations.(a) /TRRL/
