摘　　要：基桩内力测试试验是获取基桩设计参数,了解基桩力学行为最直观、最可靠的方法,其结果在工程中具有举足轻重的作用。但在静压管桩的内力测试试验中,由于静压管桩的特殊制作工艺,在桩身设置应变计一直是个难题。笔者所在课题组结合静压管桩在东北地区推广应用的多项科研实践,提出了一种桩身应变计设置方法。试验与应用结果表明,该方法在以端承为主的东北地区可靠性较高、效果良好。本文详细介绍了该方法,期与同仁交流探索,以进一步推动静压管桩的应用。The internal force test of pile is the most objective and reliable method to obtain design parameters and to understand the mechanism of pile. The result of test is very important in engineering. However, installing strain gauges in piles are difficult problems which are caused by the special producing techniques of the statically pressed pipe pile. A solution during applying the statically pipe pile in the northeast area is put forward. It proves to be an objective and reliable method in the northeast area. The paper introduces the method in detail, which aims at communicating with other researchers and further improving the application of the statically pipe pile.
