摘　　要：为解决基桩静载试验中堆载法与锚桩法的工程局限性,提出一种新型反力法。即在工程桩植入高强度螺纹钢筋作为锚桩提供反力。通过具体工程实践,重点介绍后植筋锚桩反力法试验设计及实施,发现该方法操作简便、安装快速,能够节约大量配重,适合狭窄场地且具有很好的经济效益。新方法丰富了静载试验检测工艺,具有很强的工程实用价值与推广价值。To address the engineering limitations of the pile stacking method and anchor pile method in static load testing of foundation piles,a new type of reaction method is proposed.Implanting high-strength threaded steel bars into engineering piles as anchor piles to provide reaction force.Through specific engineering practice,this paper focuses on the design and implementation of the post planting reinforcement anchor pile reaction method test.It is found that this method is easy to operate,fast to install,can save a lot of counter weight,is suitable for narrow sites,and has good economic benefits.The new method enriches the static load testing process and has strong engineering practical value and promotion value.
