摘要
随着埋深不断增加,输水隧洞由埋深产生的内水压力相应增大,普通钢筋混凝土衬砌结构已不能满足承载要求。为此,对北京市南水北调中线配套工程东干渠工程的隧洞预应力衬砌结构设计进行了探讨研究。结果表明,利用现有成熟技术采用压浆式预应力复合衬砌可以满足该结构的适用性和耐久性要求。
Along with the increase of the buried depth, the internal water pressure caused by the buried depth of water convey- ance tunnel is correspondingly increased, and then the conventional reinforced concrete lining structure can no longer meet the relevant load bearing requirement. Therefore, the design of the pre-stress reinforced concrete lining structure of the tunnel for the East Main Canal the ancillary works to the Mid-Route of the South-to-North Water Transfer Project is discussed and studied. The result shows that the requirements of both the applicability and the durability of the structure can be satisfied by the applica- tion of grouting pre-stress composite lining with the existing mature technology concerned.
