桩基快速荷载试验技术在新加坡柔佛捷运 项目中的应用.

In view of the problems that traditional static load test (SLT) takes a long time, large site occupied and high risk, the Rapid Load Test (RLT) method was introduced in Johor Bahru-Singapore Rapid Transit System project. The basic theory of RLT was introduced, and RLT and SLT correlation tests were conducted on test piles. The results show that the settlement under RLT test is smaller than that under static load test, so correlation correction should be carried out if RLT is used to replace SLT in the working load test of piles in the project, the skin friction and end bearing forces obtained from RLT and SLT of rock socketing piles are differentially distributed, and friction force in the RLT test is relatively more concentrated at the bottom compared to the SLT, while the total values of friction and end bearing forces are comparable to the results of the static load. It is feasible to use the RLT test as an alternative to the static load test in the geological condition of Bukit Timah Granite in Singapore. [ABSTRACT FROM AUTHOR]
