摘要

低应变法应用于基桩完整性检测时,由于受地质条件、桩身材料、桩型、桩长以及激振能量等因素影响,有效检测深度因具体工程而不同。实际检测中发现管桩的有效检测深度尤为局限。笔者在总结管桩有效检测深度影响因素的基础上,结合典型管桩工程的低应变试验结果,探讨增加管桩低应变法有效检测深度的方法,并为其他工程实践提供参考。
        Due to the influence of geotechnical condition, pile material, pile type, pile length and impact energy, the effective investigation depth differs from project to project when low-strain approach is applied in pile integrity tests. In real pile tests,it is usually found that the investigation depth of pipe pile is very limited. Based on summary of influencing factors on effective investigation depth and typical low-strain test data of pipe pile, an effective approach to increase effective investigation length of low-strain testing of pipe pile is discussed. This approach is also used to provide reference for other real projects.
