摘要
锚固岩质边坡具有良好的抗震效果,为深入了解其地震动响应机制,系统梳理了地震荷载下锚固岩质边坡动力响应的国内外研究文献,论述了地震作用下岩质边坡-锚固结构体系动力特性、锚固岩质边坡动力稳定性及其动力响应影响因素.基于现有研究成果,未来可进一步分析强震或频发微震等不同地震荷载形式下的锚固岩质边坡动力演化模式;借助基于演化模式的锚固岩质边坡地质力学模型,明晰地震荷载传递规律、锚固结构力学演化特征与锚固岩质边坡动力响应特性,综合揭示岩质边坡-锚固结构体系地震动耦联作用机理;开展具有大塑性变形能力的新型抗震锚固结构设计关键技术的创新、集成与标准化,并建立新型抗震锚固结构关键技术应用示范区.
The anchored rock slope has great anti-seismic effect,hence its dynamic response mechanism under earthquake is worthy of in-depth understanding.In this paper it systematically reviews the literature on the seismic dynamic response of anchored rock slope.The dynamic characteristics,dynamic stability,and factors influencing dynamic response for anchored rock slope under earthquake are discussed.Future research includes three aspects.Firstly,the dynamic evolution pattern of anchored rock slope under different earthquake types such as macroseism or frequent microseism will be analyzed.Secondly,through the geomechanics model of anchored rock slope based on evolution mode,scholars will reveal the transmission law of seismic load,the mechanical evolution process of anchorage structure,the dynamic response characteristics of anchored rock slope,and the coupling mechanism of rock slope-anchorage structure system under earthquake.Thirdly,innovation,integration,and standardization of key technologies for new anti-seismic anchorage structures with severe plastic deformation will be carried out.Application demonstration area of key technologies for new anti-seismic anchorage structures will be established.
