【摘要】 收集了西昌市已有的土层钻孔资料及有关报告,在此基础上踏勘布置了具有一定代表性的钻孔,逐个进行了剪切波速度的测定。对所有的剪切波速资料进行了整理,通过回归分析方法给出西昌市场地不同土类剪切波速与土层深度的关系式,为西昌市防震减灾规划土层地震反应分析提供土层的背景资料和分析依据,同时,也为西昌市以后的地震危险性、建筑工程场地分类以及抗震设防小区划提供有意义的参考资料。更多还原

【Abstract】 The existing soil drilling data and related reports have been collected in Xichang city,and certain typical drillings are arranged,and shear wave velocities are measured one by one.All the shear wave velocities have been sorted,the relationship between shear wave velocities and soil depths are obtained through the regression analysis.The data are not only the background information and the basis of analysis for seismic analysis of soil layers in Xichang earthquake disaster reduction planning,but also provide meaningful references for Xichang earthquake risk and site classification in future.更多还原
