瓯江北支管线盾构始发井设计

Design of originating shaft Oujiang north branch line shield

以甬台温天然气管道工程中瓯江北支盾构为例,根据工程地理位置及地质条件,对始发竖井设计进行了研究,通过结构比选和稳定性计算,确定了合理的支护形式,为竖井施工提供了依据。

Taking Oujiang north branch shield in Yongtaiwen natural gas pipeline project as an example,according to the engineering geographical location and geological condition,researched the originating shaft design,by structures comparison and stability calculation,ensured reasonable support form,provided basis for shaft construction.
