微幅振荡试验由于激振能量小,操作简单、灵活,实用经济,适于普查,在实践中得到了广泛的应用.本文在单桩承载力的确定方面扼要地对常用的几种方法进行了讨论,并探索了其理论依据及适用条件,以促进动力检测方法的正确应用和发展。 The micro-oscillation test has the advantages of small excitation energy, simple operation, flexibility, practicability and economy, suitable for census, and has been widely used in practice. This article briefly discusses several commonly used methods for determining the bearing capacity of a single pile. Discussed and explored its theoretical basis and applicable conditions to promote the correct application and development of dynamic detection methods.
