Abstract

Here, the load test series of the foundation models subjected to vertical axial loading are presented. The loading test of the wooden foundation follows the procedure that is modified from the Constant Rate of Penetration test which provides better results in the expressions of loaddisplacement curves. Using the modified CRP procedures, the more load-displacement points can be gained every load test. In this investigation, there are two models typically tested; the first model consist of 40cm×40cm raft combined to 4 piles with 3 cm in the diameter of and 60 cm of length, the second one is 30cm×60cm raft combined to 2 piles with the diameter of 7 cm and the length of 150 cm. The centre to centre spacing of the piles is set to be 5 times the diameter of the piles. The maximum capacities of the foundations can be estimated from load-displacement curves resulting from the tests. Then, the behaviour of the raft-pile foundation in term of loaddisplacement is then investigated. Using the proposed formula, it was found that the efficiency of raft-pile system reach the value more than 100%. Keywords: Raft-pile foundation, floating pondation, load test
