Subway open cut station uplift pile single-pile vertical uplift static load test method
The invention discloses a subway open cut station uplift pile single-pile vertical uplift static load test method. The subway open cut station uplift pile single-pile vertical uplift static load testmethod is characterized in that fender piles of a station open cut foundation pit enclosure structure serve as supporting points, support counterforce of a single-pile vertical uplift static load testis provided, steel cross beams and an integrated force measuring unit are assembled in a segmented mode, and the problem of detecting the bearing capacity of uplift piles of the urban rail transit open cut station in a narrow space is solved. According to the method, due to the fact that the station enclosure structure is utilized, the steel cross beams and the integrated force measuring unit canbe repeatedly used, the test cost is low, the economic benefit is considerable, and good application and popularization prospects are achieved.
一种地铁明挖车站抗拔桩单桩竖向抗拔静荷载试验方法，其利用车站明挖基坑围护结构的围护桩为支承点，提供单桩竖向抗拔静荷载试验的支座反力，分段拼装钢横梁和一体化测力单元，解决了狭小空间内城市轨道交通明挖车站抗拔桩承载力检测问题，提出了一种地铁明挖车站抗拔桩单桩竖向抗拔静荷载试验方法。因利用了车站围护结构，且钢横梁及一体化测力单元可重复利用，试验成本较小，经济效益是可观的，具有较好的推广应用前景。
