The design of underground structures and the role of geology and engineering geology is presented.

The design of underground structures and the role of geology and engineering geology is presented.

<p>For more than a century, Parsons Brinckerhoff (PB) has been instrumental in advancing state-of-the-art design and construction of underground structures, and the fields of seismic design and earthquake engineering are no exceptions. Almost three decades ...

This study defines the basis for the aseismic design of subsurface excavations and underground structures. It includes a definition of the seismic environment and earthquake hazard, and a review of the analytical and empirical tools that are available to the ...

<p>This paper presents a simplified seismic design method for underground structures based on the shear strain transmitting characteristics from surrounding ground to the structure. Since seismic deformation in the cross section of underground structures is ...
