以杭州萧山机场公路改建工程静载试桩为例,分析介绍了大吨位钻孔灌注桩静载试桩目的、试桩选择、锚桩布置、加载反力系统设计,对试桩结果进行了分析整理,并与设计理论值进行了对比。静载试桩的实施对于指导工程基桩设计,确保基桩工程的安全性和合理性具有指导意义,达到了预期目的。第二组静载试桩加载吨位达3 600t,其成功实施对今后类似大吨位静载试桩的实施可起到很好的借鉴参考作用。
Taking Hangzhou Xiaoshan Airport Highway Reconstruction Project static load test as an example, the paper introduces the purpose of static load test of large tonnage cast-in-place bored pile, the selection of test piles, the design of anchor piles and the design of reaction load system, and analyzes the results of test piling Finishing, and compared with the theoretical value of the design. The implementation of static load test pile is instructive for guiding the design of foundation pile and ensuring the safety and rationality of pile foundation project, and has achieved the expected purpose. The second group of static load test pile loading tonnage of 3 600t, its successful implementation of similar large tonnage static load test pile can play a good reference for reference.
