摘要

摘要: 通过理论分析和测试试验,对钻孔灌注桩桩底沉渣厚度的检测方法进行了研究,并开发了贯入式沉渣厚度检测系统。该系统使用便携式的ARM机替代计算机进行数据的采集和显示,并基于eMbedded C++开发了数据采集与分析软件,通过寻找沉渣与天然地层的分界面位置来确定沉渣厚度。最后通过试验对该系统的测试精度和对测试环境的要求进行了研究。结果显示,该方法的测量误差在0.01～0.09 cm之间,并且受不同测试环境的影响较小,能够较好地完成桩底沉渣厚度的检测。

Abstract: Based on the theoretical analysis and experimental tests, a detection method for bottom sediment thickness of bored piles is studied. Further, a penetration test system to detect the bottom sediment thickness of bored piles is developed based on the bottom sediment definition of piles and its mechanical properties. EMbedded ARM computer is used to collect data in this system, and the system control software is developed by Microsoft eMbedded Visual C++ 4.0. By detecting the interface between sediment and natural clay, the bottom sediment thickness of piles is measured. Finally, the precision and environmental requirements of the system are analyzed through field tests. The results show that the proposed method can complete accurate measurement of sediment thickness with error of only 0.01~0.09 cm and little effect on test environment.
