Most foreign codes on steel corrugated pipe structures involve the field of pipe culvert engineering, such as Canadian code for design of highway bridges [4] (hereinafter referred to as chbdc), American code for design of highway bridges (AASHTO) [5], modern drainage design (AISI) [6], Korean guide for design and construction of corrugated steel plate structures (2001) [7] Japan’s common ditch design guide [8] (hereinafter referred to as Japan’s Guide)..

The numerical simulation and experimental results agree well with the acceleration time history, and the acceleration amplification coefficient and its Fourier amplitude spectrum are consistent, which verifies the rationality of the finite element model.

At present, China is ushering in the construction climax of underground comprehensive pipe gallery.

Precast steel corrugated pipe gallery structure has the advantages of green environmental protection, light weight, easy transportation, short construction period and good coordination with soil deformation.

The current technical code for urban comprehensive pipe gallery Engineering (gb50838-2015) [3] calculates the seismic design of urban comprehensive pipe gallery as class B buildings, but the code does not give a specific calculation method for seismic design, and the code is mainly aimed at reinforced concrete structures.

It is a new pipe gallery structure put into engineering application in recent years.

The construction and development of underground comprehensive pipe gallery has become an important direction for countries and cities to seek social sustainable development and has been promoted to the national development strategic position [1-2].
