2、ion method of the multi-arch tunnel group is discussed by using an engineering example of Metro Line 3. In the construction of the subway, the construction technique of changing a multi-arch tunnel into a single-hole tunnel was first proposed. The technical solutions of the single-middle wall and th

3、e separated middle-wall structure were compared and selected to meet the requirements of structural safety, construction safety, and economic efficiency. Good technical solutions can provide reference and reference for the design and construction of similar projects in the future.Keywords: multi-arc

4、h tunnel group, single middle partition wall, separated middle partition wall, construction technologyBecause of the design requirements of the subway tunnel, a variety of tunnel structures are required. Among them, a multi-arch tunnel segment consisting of unequal cross-linked arches and tiple-arch

This article combines the project example according to the geological conditions of the tunnel, the time limit requirements through conparison and selection of the best construction program that can achieve rapid co

In the section DK3016.047037.157, a tunnel group with unequal spans with double arches and tiple arches was set ip. Uneq

The triple-arch tunnel excavation span is 19.9m and the 7.885m cross-vector ratio is 1

The surrounding rock of the section of the multi-arch tunnel is from top to bottom: artificial backfill, red sand and alluvial sand layer, alluvial-diluvial earth, fluvial-lacustrine sedimentary soil, plastic residual soil, hard plastic-hard residue.

The thickness of the vault covering the tunnel is 15.518m, and the thickness of the surrounding rock layer IV is 5.67.6m. The buried

The construction process is complex and the const

Therefore, it is very important to choose a good construction scheme to complete the construction of the multi-arch tunnel section with high quality and efficiency. When selecting a construction plan, the following aspects are mainly considered:

12、 1 Construction safety and construction Safety 2 Construction difficulty 3 Construction cycle 4 Economic benefits. Based on these four principles, the following two construction plans were selected for conparative selection through the research and demonstration of the construction plan.2.1Single Wa

Aft

This construction method is applied to the general construction methods of domestic double-arch tunnels in Guangzhou Metro, Nanjing Metro and Beijing Subway, and can safely and smoothly complete the construction of tunnel groups. However, the study of previous engineering examples and construction techn
