摘要
结合某一实际工程,在大致相同的场地条件下,对基桩采用锚桩法、反力桩法与自平衡法进行试桩测试。通过对试桩测试结果进行对比分析,验证了在实际工程中采用自平衡法试桩结果的可靠性及准确性,提出可将自平衡法实测值乘以修正系数0.9的建议。同时通过对桩侧埋设的钢筋计所测得出的桩侧阻力进行分析,得出自平衡法和反力桩法两种不同试桩方式间的受力差异关系。
Combined with a real project, piles were tested by using the anchor pile method, reaction force pile method and self balanced pile method under roughly the same site conditions. Through the comparative analysis of the test results of piles, the accuracy and reliability of the results by self balanced pile method in practical engineering were verified, and the measured value by self balanced pile method was recommended to multiply the correction coefficient of 0. 9. Through the analysis of the pile side resistance by using the embedded reinforcement meter on the pile side, mechanical difference relationship can be obtained from two different test pile methods of self balanced pile method and reaction force pile method.
