Abstract:

Based on theoretical analysis and experimental tests, a detection method of bored pile bottom sediment thickness was studied. Further, a penetration test system applied to detect bored pile bottom sediment thickness was developed based on pile bottom sediment definition and its mechanical property. Embedded ARM computer was used to collect data in this system and system control software was developed by Microsoft eMbedded Visual C++ 4.0. By detecting interface between sediment and natural clay, pile bottom sediment thickness was measured. Finally, this system’s precision and environmental requirement were analyzed by field test. The result showed that this method can complete accurate measurement of sediment thickness with only 0.01~0.09cm error and little effect on test environment.
