大断面TBM组装洞室设计与施工

TBM在隧洞内组装,受场地、空间限制,对组装进度影响很大,因而组装洞室设计与施工、关键设备选型、组装方案、场地布置等就愈发显现其重要性;同时由于组装洞室断画大、工程量大、施工工艺复杂、施工质量要求高,因而需要予以高度重视.文章以锦屏二级水电站引水隧洞为实例,介绍如何根据设备参数、地质条件和组装方案进行大断面TBM组装洞室的设计及施工,可供类似工程借鉴.

Design and Construction of TBM Assembly Chamber with Large Cross-section

Limited space affects the assembly of TBM in the tunnel chamber, restricting the assembly progress.Design and construction of the assembly chamber, selection of key equipment, assembly scheme and site layout are important elements to be considered. Taking Jinping II hydropower station diversion tunnel as an example, the thesis introduces the design and construction of the large cross -section TBM assembly chamber according to equipment parameters, geological conditions and assembly scheme. The practice can ...
