Development status and trend analysis of physical simulation experiments for geological hazards
摘要
Abstract
[Significance]Over the past 20 years,physical simulation experiments for geological hazards have rapidly developed,evolving into an interdisciplinary field with widespread applications and continuous technological advancements.Analyzing the current status and trends of physical simulation experiments for geological hazards helps researchers gain a comprehensive understanding of the field,design experiments,develop equipment,and update technologies aligned with future directions,thereby promoting innovation in key theories related to geological hazards.[Progress]This paper reviews a significant body of domestic and international literature on physical simulation experiments of geological hazards,summarizes five key significances of conducting such experiments,and analyzes the current status of six core physical simulation technologies.Model box and flume are the most widely used simulation technologies due to their versatile combinations,low cost,ease of installation,and simple operation.Base friction simulation technology enables coupling between the model and the gravitational field in two-dimensional settings.Shaking table and centrifuge technologies,while expensive to build and operate,provide controlled vibrational and gravitational conditions,playing an indispensable role in physical simulation experiments.In-situ simulation technology,while facing challenges such as long experimental cycles,difficult model fabrication,high personnel input,low automation,and poor repeatability,offers distinct advantages by mitigating issues such as scaling effects,boundary constraints,and gravitational distortion.[Conclusions and Prospects]Physical simulation experiments for geological hazards are evolving toward greater scenario complexity,larger-scale testing,more scientific material selection,and intelligent data collection.These advancements impose higher demands on experimental technologies and economic costs,highlighting the urgent need to foster a conducive development environment.Doing so will enable physical simulation technology to play an even greater role in geohazard research.关键词
