Abstract

Abstract:

DajuyuanKexueguan running tunnel of Shenzhen Metro ("DaKe running tunnel" in short) consists of a crossover tunnel section, which is a shallowburied tunnel section with complex structures. The article presents in detail the advance consolidation scheme, construction sequence and excavation method of the crossover tunnel section, as well as the special consolidation scheme of the tunnel section crossing beneath the vital positions of the gas pipes. The article can provide reference for the construction of works under similar circumstances in the future.

Key words: , Metro crossover design construction
