大型敞开式TBM组装洞室布置及吊装方案比选

Layout and Hoisting Scheme Comparison of Large Open-type TBM Assembly Cavern

随着长大山岭隧洞工程建设的不断发展,长大山岭隧道/洞敞开式TBM施工技术应用前景广阔。大型敞开式TBM洞内组装方案需结合工程地形地貌、工程布置和组装洞室条件进行优选。在建设工期压力下,对组装洞室布置及吊装方式进行研究比选,选择最优组装方案,以满足项目工程建设的需要。

With the continuous development of long-distance mountain tunnel construction,open-type TBM construction technology has broad application prospects.The assembly scheme of large open-type TBM tunnel needs to be optimized in combination with engineering topography and landform,engineering layout and assembly chamber conditions.Under the pressure of construction period,this paper studies and compares the arrangement and hoisting method of assembly chamber,and selects the optimum assembly scheme to meet the needs of project construction.
