摘要

A series of model tests on NSF on pile groups under variety surchargeloading were designed and conducted. During the tests, pile strain,settlement of pile and soil were measured. The results indicate thatwhen side load increases from 20kPa to 120kPa, the neutral plane ofthe single pile varies from 0.82 L (length of pile in sand) to 0.93 L. Pilehead settlement and negative skin friction under side load were smallercompared with the results of the test under uniform loading, while thelocation of neutral plane was lower.
