摘要
结合天津地铁6号线南河庄至大毕庄段盾构隧道施工实例,对与隧道垂直埋深3 m的航油管线及其周围土体进行了现场检测,研究了盾构施工对既有地下管线的影响,通过埋设沉降板与应变传感器,获取了管线周围土体的沉降数据以及管线的应变数据。
Combining with shield tunnel construction example of Nanhezhuang-Dabizhuang section of Tianjin subway line No. 6,the paper carries out in-situ examination of aviation gasoline pipeline with 3 m of vertical buried-depth and surrounding soil body,and studies the impact of shield construction upon existing underground pipeline. Through embedding subsidence board and stress sensor,it acquires the subsidence data of soil body surrounding the pipeline and pipeline stress data.
