摘　　要：依托港珠澳大桥西人工岛大直径钢圆筒成岛工程,对实际工作状态的大直径钢圆筒土压力进行监测,填补了大直径钢圆筒受力实测数据的空白。通过工程实测大直径钢圆筒土压力,客观地反映了钢圆筒工作状态下的土压力分布形式和分布规律。通过理论计算钢圆筒的主动土压力、静止土压力和被动土压力与实测数据对比,得到了典型钢圆筒的工作状态是稳定的。实测结果为大直径钢圆筒的稳定计算和施工提供了可靠的基础数据。The earth pressure on large-diameter steel cylinders in actual working conditions was monitored based on the island-building project of the west artificial island of Hongkong-Zhuhai-Macao Bridge,filling up the blank in measured data of large-diameter steel cylinders.The measured earth pressure on large diameter steel cylinders in actual works objectively reflects the distribution form and law of earth pressure under the working condition of the steel cylinders.By comparing the theoretically calculated active earth pressure,static earth pressure and passive earth pressure on steel cylinders with the measured data,it is concluded that the working state of typical steel cylinders is stable.The measured results provide reliable basic data for the stability calculation and the construction of large-diameter steel cylinders.
