摘要
桩基完整性检测对于建筑工程的安全、质量、寿命和经济效益等方面都具有重要意义,是确保工程建设质量的重要环节。本文采用低应变反射波法对某桥梁桩基的完整性进行检测,建立了各种类型的缺陷桩模型;考虑到桩基材料特性、桩周土参数、边界条件和阻尼系数对反射波的影响,对桩基进行数值模拟,将实际检测结果与数值模拟结果进行比较。
The integrity detection of pile foundation is of great significance to the safety,quality,life and economic benefits of construction projects,and is an important link to ensure the quality of construction projects.In this study,the integrity of the bridge pile foundation was tested by low strain reflection wave method,and various types of defective pile models were established.Considering the influence of pile material properties,soil parameters around pile,boundary conditions and damping coefficient on the reflected wave,the pile foundation was simulated numerically,and the test results were compared with the numerical simulation results.
