摘要
在桩基静载荷试验中,当埋设有测量桩身应力的传感器时,可以利用桩身应力计算桩周土分层的侧阻力和桩端土的端阻力。本文利用上海地区某工程3根桩的实际测试结果,介绍一种精度更高的利用双循环加载测试桩周土阻力的一种测试方法。
On static load test of pile,the pile bottom resistance of pile-end soil and the lateral friction resistance of pile side layered soil can be calculated by pile stress when sensors using to measure pile stress are embedded.According the actual test results of three piles finished in Shanghai,a test method is introduced in the paper that testing resistance of soil around pile through more accurate bicirculating load test.
