【摘要】 通过分析由强烈地震引发的场地振动、地面破裂、地基失效和边坡破坏等震害效应令高架交通工程的墩桩基础产生位移、下沉、变形、折断,进而导致高架线路交通工程遭到破坏的实况,提出了一些基于工程场地地震安全性评价的高架线路场地地震地质灾害防御对策与工程地震勘测的建议。更多还原

【Abstract】 The paper analyzes the severe earthquake effects of ground vibration,land surface rupture,foundation failure and slope landslide on high-elevated transport engineering structures,which usually lead to displacement,sink,deformation and fracture of pier-type foundation of structures and thus produce severe damages to structures.Based on thorough analysis,this paper presents major prevention treatments against seismic geological disaster effects on high-elevated transport engineering structures and makes suggestions on engineering seismic surveys from the aspect of seismic safety evaluation of engineering sites.更多还原
