高应变动测试验在水下桩基施工中的应用

摘要

结合东海某导管架平台桩基进行的水下高应变动测试验成功案例，论述了试验内容及特点；利用CAPWAP对现场数据进行了分析。现场实测数据显示，在打桩过程中桩身的最大拉、压应力均小于许用应力，桩身完整性较好。%Combing with the successful case that the high strain dynamic test on the pile foundation of a jacket platform in the East China Sea, we described and discussed the test in detail, summarized the characteristics of the test, and analyzed the field data by CAPWAP. The data obtained from the test are presented to show that the maximum tensile and compressive stresses are lower than the allowable stress, and the integrity of piles is good.
