钻芯压水试验在基桩完整性检测中的应用与分析

Application and Analysis of Core Drilling Water Pressure Test in the Integrity Detection of Foundation Pile

结合水利工程压水试验,介绍了压水试验的原理及试验方法,提出该试验方法在基桩完整性检测中应用的可行性。结合工程实例,应用声波透射法、钻芯法及压水试验对混凝土灌注桩接桩质量进行综合评定。

Combined with the water pressure test of hydraulic engineering,the paper introduces the principle of water pressure test and experimental method,and it puts forward feasibility of the method in the application of pile integrity testing.Based on engineering examples,it comprehensively evaluates the pile extension quality of bored concrete pile through cross-hole sonic logging,core drilling method and water pressure test.
