深中通道西人工岛大直径钢圆筒实测土压力研究. (Chinese)

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.
