SV波入射下饱和地层浅埋平行隧道动力响应机制

open access: yesDizhen xuebao, 2022
目前城市核心区交叠紧邻的隧道群大量涌现,其抗震安全性问题日益突出,但近邻隧道之间以及与地层的动力相互作用机制尚不清晰。本文针对饱和地层浅埋平行隧道,基于Biot两相介质理论,采用边界积分方程法分别建立了饱和地层水平和竖向双线隧道动力作用分析模型,并与典型算例精确解对比验证了本模型的有效性;在此基础上,研究了SV波入射频率变化和双线隧道间距变化对隧道结构及周围地层孔隙水压力的影响机制,并以单条隧道分析结果为参照进行对比分析。结果表明:相比单条隧道,相邻隧道的存在改变了既有隧道的动力响应特征 ...

The key characteristics concept

open access: yesCurrent Opinion in Toxicology
In evaluating whether a chemical can cause cancer or another adverse outcome, three lines of evidence are typically considered: epidemiology, animal bioassays and mechanistic evidence. The key characteristics (KCs) form the basis of a uniform approach for searching, organizing, and evaluating mechanistic evidence to support hazard identification.
