Analysis of Construction Schemes for Shallow-buried Tunnels with Small Distance Between Centers Under Complex Geological Condition
Tunnel engineering is often the most difficult and complex part of the entire construction pro-ject due to its difficulty and complexity in construction.Especially for small distance between centers shal-low-buried tunnels under complex geological conditions,the quality of construction scheme directly affects the safety and quality of tunnel construction.This paper takes Xing Shan Expressway Daqishan Tunnel as a case study,introduces the construction scheme and technical characteristics of this type of tunnel in detail,and provides guidance for the future construction of similar tunnels.
