摘要
通过施工实践中的技术体会,简要介绍了中长隧道快速施工关键技术,对类似工程的施工具有一定借鉴意义。
with the development of economy, the highway network is become more and more perfect. However, the prestressed concrete continuous curved box girder is adopted during design because the topographty, bridges and so on when the with the highway extend the mountainous area. As a example, this paper introduce key control tecnnique of the bracket, quality, prestress and grouting etc during the Lan Mu bridge construction of continuous box girder in the nine contract of Yu Shan highway. At same time, a quality resume is given for the eccentric, super - long steel strands and grouting which .may serve as a referenee for the construction of similar engineering.
