摘要
采用基桩高应变动测判定基桩承载力和评价桩身完整性,可以获得比静载试验更加丰富和详细的信息。文章结合预制桩工程实例,通过基桩高应变动测与静载试验相结合,进一步了解反映桩端阻力大小的高应变动测曲线特征规律,以提高基桩高应变动测技术,提供可靠的高应变动测成果。
More detailed information about the bearing capacity and integrity of the pile can be obtained by high strain dynamic test than by dead-load test. Through the comparison of the high strain dynamic test and the dead-load test made on the prestressed pipe pile, the article approaches to the rules of dynamic strain curves that reflect the resistance value at pile end. It is hoped that the study made in the article may help to improve reliability of high strain dynamic test.
