| 摘 要： | 摘要：本文首先基于CAPWAP_C法,针对现有高应变检测拟合方法的局限性,分别推导出传感器距桩顶4个单元内的力波与速度拟合公式。然后根据推导所得的公式编制计算程序,拟合出传感器在不同位置时的力波与Zv图,并分析传感器安装位置对最终拟合曲线的影响。最后将所得的力波与Zv图与原方法拟合所得到的力波与Zv图以及实测F-Zv图进行对比分析,论证改进方法的优异性,更符合工程实际。

| Abstract: | Based on CAPWAP_C method,aiming at the limitations of the present PDA method,the fitting formulas between force wave F and velocity v within a distance of 4 elements from pile top to sensors for a high strain pile were deduced.According to the deduced formula,the calculation algarithm was programmed.Then,the(F-Zv) plots were frawn with different positions of the sensor.And the influences of the positions of the sensor on the fitted currves were analyzed.The F-Zv curres obtained with the proposed method were... |
