摘要
为研究安徽省宿州市的岩土工程性质,选用单孔法波速法测试,在实验区取三个钻孔,对各个钻孔不同岩土层的波速值及动态参数多次测量并进行统计分析。结果表明:实验区各层土岩性各异,最上层淤泥质黏土的抗动力变形能力较低,动力变形较强,选取地基场地工程性质不稳定;而钻孔最底层微风化花岗岩抗动力变形能力较强,动力变形能力较低,地基场地工程性质较稳定。如果进行场地建设,可以选取最底层作为地基。
In order to study the geotechnical engineering properties of Suzhou City in Anhui Province, the wave velocity valueand dynamic parameters of different rock and soil layers in three boreholes were measured and statistically analyzed. The results showthat each layer of soil in the experimental area is different in lithology, and the resistance to dynamic deformation of the uppermostmuddy clay is lower, and the dynamic deformation is stronger, and the engineering properties of the selected foundation sites are unstable. On the other hand, at the bottom of the borehole, the aeolian granite has strong resistance to dynamic deformation, low dynamic deformation ability and stable engineering properties of the foundation site. If the site construction, you can select the lowestground as a foundation.
