土压平衡系统正在越来越多地用于解决在困难地质情况下隧道施工问题。在隧道的开挖面上,其原理看起来是相对简单的。但对于特定的工程,决定最好类型的开挖面支承应使用合理的步骤。
Earth pressure balance systems are increasingly being used to solve tunnel construction problems in difficult geological conditions. The principle of excavation in tunnels appears to be relatively straightforward. However, for a particular project, reasonable steps should be taken to determine the best type of face excavation support.
