- Abstract:
- The stress wave speed is the necessary condition to make sure pile length and pile defects positionin low strain integrety testing of foundation pile with the stress wave echo method. Quantilying the stress wavespeed is very dificult, because it is affected by multi-factors. This has been the boleneck in point for develo.ping test technology of foundation pile, In this paper, some factors affecting the stress wave speed were ana-lyzed according to stress wave theroy and experiment results, the quantity relalionships of the stress wave speedin pile and time and concrete age were determined. lastly, five brief methods to quantifying the siress wavespeed in pile were presented to control pile quality for test engineers according engineering practice.
