摘要
在交通发展过程中,桥梁建设规模越来越大,在桥梁桩基施工过程中,单桩承载力与其整体施工质量息息相关,因此检测单位应对桥梁单桩承载力实施检测,当前常见的检测方式主要有高应变动测法和静载试验法两种,由于高应变动侧具有检测效率高、费用低、耗时短、检测过程简单等优点,因此,其应用越来越广泛。该文首先对高应变动测法的检测原理进行阐述,并对当前高应变动测法准确性影响因素和解决措施进行分析,最后,以实际工程为依据,对桥梁桩基检测过程中高应变动测法的实际应用过程进行分析,确保桥梁桩基承载力符合施工要求,旨在为今后桥梁桩基检测奠定基础。
In the process of traffic development, the scale of bridge construction is getting larger and larger. In the process of bridge pile foundation construction, the bearing capacity of single pile is closely related to the overall construction quality. Therefore, the testing unit should test the bearing capacity of single pile of bridge. Currently,there are two common testing methods: high stress dynamic testing method and static load testing method. Due to its advantages of high detection efficiency, low cost, short time consumption and simple detection process, the application of high strain variable side is more and more extensive. This paper first expounds the testing principle of high strain dynamic testing method, and analyzes the factors affecting the accuracy of the current high strain dynamic testing method and the solutions. Finally, based on the actual project, it analyzes the actual application process of high strain dynamic testing method in the process of bridge pile foundation testing to ensure that the bearing capacity of bridge pile foundation meets the construction requirements, aiming to lay a foundation for future bridge pile foundation testing.
