摘要
新密市某局拟建的 16层综合楼位于第四系覆盖的岩溶发育区。为有效评价隐伏型岩溶地段带来的不稳定性因素 ,有必要查明区内浅层溶洞的发育规律及分布特征。进而为高大建筑物选址及地基处理方案提供决策的依据。本文通过微重力测量结合高密度电法对相关地区进行详细勘查 ,基本查明了区内浅层溶洞的平面分布情况和空间展布形态 ,从环境地球物理角度对工程选址及地基处理提出了合理的建议 ,得到了建筑设计部门的高度评价。
The sixteen-storied comprehensive building of one office lies in the karst region covered by Quaternary in Xinmi City.It is necessary to ascertain developing regulation and scattering feature of the shallow karst cave in order to effectively appraise unstable factors brought by hidden karst terrain.From this,it may provide strategic for selecting address on high building and plan of foundation treatment.This paper finds out the distribution in plane and shape in space about the shallow karst cave by mean of microgravity measurment combined with high density electrical prospecting,and poses the rational suggestion for selecting project address and foundation treatment in view of environmental geophysics. This suggestion gains high value from the building design department.
