摘要
基于6线并行的轨道交通区间隧道工程,研究了在城市施工场地受限、河道水网密集、地质条件复杂的环境下多线并行小净距矿山法与盾构法隧道设计方案。探讨了盾构井布置和盾构接收方案、双线矿山法隧道与盾构隧道分叉衔接方案的设计原则及适用条件,并采用有限元计算论证小净距单洞矿山法隧道与盾构法隧道并行方案可行性,为今后类似工程提供参考。
Based on the 6-line parallel rail transit interval tunnel project,the design schemes of multi-line parallel small clear distance mine tunnel and shield tunnel are studied under the environment of limited urban construction site,dense river water network and complex geological conditions.The design principles and applicable conditions of shield shaft layout and shield receiving scheme,bifurcated connection scheme between double line mine tunnel and shield tunnel are discussed,and the feasibility of parallel scheme between small clear distance single tunnel mine tunnel and shield tunnel is demonstrated by finite element calculation,so as to provide reference for similar projects in the future.
