摘　　要：插入式大直径钢圆筒快速成岛技术是近年来国内快速发展的一项新兴技术。依托深中通道西人工岛工程,通过在筒身布设土压力计,对钢圆筒在成岛过程中各个工序下的受力状况进行监测,数据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;对比分析钢圆筒主动、静止和被动土压力的理论计算值,可判断其工作状态及稳定性,为类似工程项目设计和施工提供参考。The rapid island forming technology with plug-in large diameter steel cylinders is an emerging technology developed rapidly in China in recent years.Based on the works on the west artificial island of Shenzhen-Zhongshan Link,earth pressure gauges were fixed on the cylinder shaft to monitor the stresses of steel cylinders in each process of island forming and the monitored data objectively reflected the distribution pattern and law of earth pressure when the steel cylinders were in their working state.By comparing and analyzing the theoretical calculation values of the active,static and passive earth pressures on the steel cylinders,the working state and stability of the steel cylinders can be judged,and may provide reference for the design and construction of similar projects.
