港珠澳大桥澳门口岸管理区轻轨预留区桩基础项目位于海上吹填人工岛,采用大直径混凝土灌注桩,桩长达55m,对某桩进行竖向抗压静载试验,单桩极限试验荷载值达58528k N,是目前广东省内土建工程单桩基础检测吨位(极限值)最大的检测项目,在特殊工况下成功检测,最大沉降29.11mm,残余沉降7.02mm,满足国家规范和澳门地区(欧美)规范要求,并为国内填海及人工岛土建桩基础检测提供了宝贵经验和数据支持。
Hong Kong-Zhuhai-Macao Bridge Macao Port Management Area light rail reserved area pile foundation project is located at the sea infill artificial island, the use of large diameter concrete bored pile, pile length up to 55m, a pile vertical compression static load test, single pile limit test The load value is 58528kN, which is the largest test item for the tonnage (limit value) of single-pile foundations in civil engineering in Guangdong Province. It has been successfully tested under special working conditions with the maximum settlement of 29.11mm and the residual settlement of 7.02mm, meeting the requirements of the national code and Macao Region (Europe and the United States) norms and requirements, and for the domestic reclamation and artificial island construction of the pile foundations provide valuable experience and data support.
