Analysis on Construction Influence of the Underpass of Oblique Crossing Subway Tunnel

Abstract:

With the rapid development of the city, the construction of underpass of adjacent subway tunnel will have influence on the safety of subway operation. Base on underground pedestrian passage engineering, the complex construction conditions of oblique crossing-over subway running tunnel for A section channel is considered, plane strain finite element simulation analysis for the excavation and support and secondary lining construction of A section channel are conducted, and two kinds of construction conditions of adjacent and crossing subway tunnel for A section channel are simulated, the influence of the construction of A section channel on adjacent subway running tunnel is also analyzed. The results were shown that the maximum floating upward value is within 1mm and almost no lateral displacement during the construction of A section channel. which meet the requirements of urban rail transit safety operation, and the basis for advanced control of underpass construction is provided.
