Abstract

Canyons, as a typical form of irregular local topography, exert a substantial influence on the distribution of seismic motion. Numerous large-scale infrastructure projects such as water conservancy and bridges have been constructed in canyon areas. The seismic amplification effect of valley terrain cannot be overlooked in its impact on the disaster vulnerability of engineering facilities in this region. This paper investigates the seismic response of a semi-circular canyon site and proposes seismic mitigation measures for the two shoulders of the canyon, namely fillets and chamfers. Utilizing numerical simulation methods, the study delves into the site response under the vertical and oblique incidence of P-waves. By comparing and analyzing the seismic mitigation effects of the two measures on the canyon shoulders, differences in their effectiveness against P-wave-induced seismic response are revealed. The research findings offer valuable insights for the design and improvement of seismic-resistant structures in canyon sites, serving as a theoretical foundation for mitigating the impact of seismic disasters. This study not only contributes to an enhanced understanding of seismic influences but also presents new perspectives and approaches for seismic engineering in terms of mitigation techniques and design.
