CORRELATING RAPID AND STATIC LOAD TEST RESULTS OF BORED PILES IN SINGAPORE

Rapid Load Test (RLT) has become a common and standard method of testing in Singapore for bored pile as it is
generally easier and faster to set-up than conventional Static Load Test, and is less complex to analyse than Dynamic
Load Test. Recently Singapore is seeing greater use of Rapid Load Test for verification of pile design parameters and
pile geotechnical capacity, in ultimate load tests, as well as, for verification of pile head settlement criteria in working
load tests. This paper summarizes results of many correlation tests conducted on bored pile, where both static load test
and rapid load test were conducted, for high-rise buildings developed by public housing agency, Housing &
Development Board (HDB), Singapore. Based on tests carried out in HDB projects, Rapid Load Test generally
provides good correlation with Static Load Test in various soil types in Singapore. This paper focus on the correlation
between Rapid Load test and Static Load Test especially in pile head load-settlement behaviour, mobilized skin friction
and mobilized end bearing.
