Structure Strengthening Method for Enhancing Seismic Behavior of Soft Tunnel Portal Section

Tunnel portal sections always suffer serious damage under strong earthquakes. This paper aims to study the seismic performance of lining strengthening method in soft rock portal section by employing the model test. Firstly, the shaking table test considering the test cases, the modified input motion...
