摘要
文中依托贵阳抽水蓄能电站项目,采用现场地质调查、勘测钻孔、资料分析等手段,开展工程场地地震安全性评价.结果表明,场地发生泥石流、自然滑坡等地震地质灾害的可能性小,不会出现砂土液化和软土震陷现象,可不考虑断层作用导致的地表错动、地裂缝与地面变形等对工程结构的影响.由于岩性及溶蚀程度的差异,地表岩溶发育特征存在明显差异,建议详细查明场地溶洞发育分布情况.
Abstract
Based on the Guiyang pumped storage power station project,the article conducts seismic safety evaluation of the engineering site through on-site geological investigation,survey drilling,data analysis,and other means.The results indicate that the likelihood of seismic geo-logical disasters such as mudslides and natural landslides occurring on the site is low,and there will be no liquefaction of sand or seismic sub-sidence of soft soil.The impact of surface displacement,ground cracks,and ground deformation caused by fault action on engineering struc-tures may not be considered.Due to differences in lithology and degree of dissolution,there are significant differences in the development char-acteristics of surface karst.It is recommended to further investigate the distribution of karst caves on the site in detail.
