高应变动力试桩技术的现存问题与改进方向

Existing Problems and Improvement Direction of High-strain Dynamic Testing Technique to the Testing of Pile

作为一种简便、经济,同时相对精确的检测方法,高应变检测技术在房屋建筑、市政桥梁、港口水工等工程的基桩承载力、完整性检测及打桩监测中得到了广泛地应用,但是无论是仪器设备等硬件抑或是信号采集、数据分析等软件,仍然存在许多局限性与不足。为了改进检测方法,提高准确度,从多个方面介绍了高应变检测技术的现存问题与改进方向,以期推动该项技术的进一步完善。

As a simple, cheap,and relatively accurate method,high-strain testing technique to the testing of pile has been generally accepted and widely implemented. However,there are still many limitations and shortcomings no matter in hardware and in software. In order to promote development and perfection,give better service to the construction requirements, based on thorough analysis, the latest developments in technology are introduced by author through extensive investigation at home and abroad.
