摘要
沙特国王港项目桩基工程总共包含灌注桩3 940根,项目中的所有灌注桩均处于吹沙填海区域。为保证灌注桩单桩竖向承载力符合相关规范,根据沙特灌注桩规范[1]要求,每100根灌注桩需选取1根进行静载试验,据此该项目共需进行40次静载试验。由于试验工程量大且试验点分布较广,采用传统的锚桩法[2]静载试验周期长、影响施工进度,而采用自平衡法桩基静载试验装置简单,省时省力且试桩可作为工作桩使用,进而节约了施工成本。阐述了自平衡法在沙特国王港项目桩基施工中的应用过程。
The foundation project of Saudi King's Port Project includes a total of 3940 piles,and all the piles in the project are located in the sand-blowing reclamation area.In order to ensure that the vertical bearing capacity of a single pile meets the requirements of the specification,according to the requirements of the Saudi concrete pouring pile standard[1],1 per 100 concrete pouring piles needs to be selected for a static load test,according to which a total of 40 static load tests are required for this project.Due to the large amount of test works and the wide distribution of test points,the traditional static load test using anchor pile method[2]takes a long time,which affects the construction progress,and pile foundation static load test using the self-balancing method is adopted.The device is simple,time-saving and labor-saving,and the test pile can be used as working piles,therefore,the construction costs are saved.This article describes the application process of the self-balancing method in the pile foundation construction of Saudi King's Port Project.
