【摘要】 对城市系统进行抗震减灾的前提,应为识别土地这一特殊的承灾体(同时又为整个城市系统的共同承载体)所潜在的地震灾害的风险,即为以地震危险性为输入,结合土地的基本属性,进行土地抗震适宜性评价。在界定土地抗震适宜性评价的定义、作用、以及范畴的基础上,研究基于空间数据的土地抗震适宜性综合评价模型。该模型综合考虑了地震危险性、液化态势、土地等效剪切波速和地面稳定性因素。更多还原

【Abstract】 As the precondition of seismic resistance and disaster reduction for all city systems,the risk identification of the earthquake disaster risk for land,which is the shared support of all city systems,considers the basic characters of land,based on the input of seismic hazard.This paper discusses the definition,function and category of land seismic resistance suitability,and researches its comprehensive evaluation model based on spatial data.This comprehensive evaluation model includes the index of seismic hazard,liquefaction trend,soil equivalent shear wave velocity and ground stability.更多还原
