以武汉某区间为例分析MJS加固情况下盾构下穿对既有区间的影响

Taking a Section in Wuhan as an Example,the Influence of Shield Penetration on the Existing Section under the Condition of MJS Reinforcement was Analyzed

叠线站台换乘因其换乘距离短、车站规模小、减少占地等优点,在地铁中被广泛采用。但建设过程中,易出现后施工区间穿越先施工区间的情况,而MJS加固可有效减少区间穿越造成的影响。本研究拟以武汉某实际工程为背景,分析MJS加固情况下,盾构隧道下穿对既有区间的影响。

Stacked line platform transfer is widely used in subway because of its advantages such as short transfer distance,small station scale and reduced land area.However,in the construction process,it is easy to cross the first construction section,and MJS reinforcement can effectively reduce the impact caused by the section crossing.This research intends to take a practical project in Wuhan as the background to analyze the influence of shield tunneling under the condition of MJS reinforcement on the existing section.
