Recent Findings from Hunan University Has Provided New Information about Mining and Metallurgy (Seismic Reliability Analysis of Shield Tunnel Faces Under Multiple Failure Modes By Pseudodynamic Method and Response Surface Method)

摘要

2022 JUL 19 (NewsRx) – By a News Reporter-Staff News Editor at Mining & Minerals Daily Daily – Investigators publish new report on Technology - Mining and Metallurgy. According to news originating from Xiangtan, People’s Republic of China, by NewsRx correspondents, research stated, “In order to investigate the stability problem of shield tunnel faces subjected to seismic loading, the pseudo-dynamic method (P-DM) was employed to analyze the seismic effect on the face. Two kinds of failure mechanisms of active collapse and passive extrusion were considered, and a seismic reliability model of shield tunnel faces under multi-failure mode was established.”
