摘要
介绍了上海福州路电力隧道及附近地下开关站基坑工程的基本情况,利用三维有限元软件进行针对运营电力隧道近距离范围的基坑开挖施工的数值仿真模拟,并结合现场实际监测数据验证了数值模型的可靠性。分析了基坑开挖施工对电力隧道主体结构的影响,给出了电力隧道保护区范围。
The paper presents the basic situation of foundation pit excavation engineering around Fuzhou Road electric power tunnel and the nearby underground switch station.By establishing a 3-D infinite element software numerical simulation model,the space of excavation around the operating electric power tunnel is calculated and the reliability of the model is testified by the on-spot actual monitoring statistics.Then the influence of foundation pit excavation on the main structure of electric power tunnel is analyzed and the protection space of the electric power tunnel is confirmed accordingly.
