桩身完整性测试对土木工程具有重要的意义.对混凝土桩采用侧向激振,分析其反射波形特征,提出了一种桩基完整性检测的新方法.文中首先用钢筋混凝土梁试件作为模型桩进行室内模拟试验,再在工程实例中将这种桩基完整性检测新方法结合传统弹性反射波法结果来进行比较分析,验证了侧向激振新方法的有效性,从而为基桩质量检测提供了一种新的可靠手段.

Pile Integrity Testing has an important significance in civil engineering. For concrete piles with lateral excitation, its reflection waveform characteristics is analyzed and a new method for pile integrity testing is proposed. In the paper first reinforced concrete beam specimen is simulated as a model pile indoor, and then in the project it will be tested by this new method.A comparative analysis is carried out by using the method and the traditional elastic reflection wave method for verifying the effectiveness of the new method with lateral excitation.A reliable new means is provided for pile quality testing.
