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
