摘要
地下电力管廊的埋深在10 m以下。长江中下游软土地基地区,常处在粉土夹淤泥质粉土土层中施工,而施工路径经常密布电力杆塔,顶管路径无法规避。结合工程施工实例,对比分析土体加固的不同保护方法,探讨安全可靠、经济有效的实施方案,对其他类似的大直径顶管施工中可能遇到的杆塔保护具有借鉴意义。
The tunnels of power underground are in the depth of more than 10 meters. In the area of soft soil foundation at the Yangtze River, they are often built in the soil layer. However, power transmission towers also constructed near the path of tunnels, which cannot be evaded. With practical engineering projects, analysis on the soil reinforcement are implemented in terms of reliability, economic and effectiveness. The research provide a reference for future similar construction projects.
