对鸡街钻孔取样和现场试验,得出鸡街膨胀土在不同压力下的膨胀率,以及各深度膨胀土的膨胀量。结合矿物成分及化学成分,分析鸡街膨胀土的胀缩性等工程特性。对鸡街土层含水率进统计,得出鸡街地区膨胀土含水率变化曲线,结合膨胀土变形量进行分析,为膨胀土地区工程建设提供了依据。
對鷄街鑽孔取樣和現場試驗,得齣鷄街膨脹土在不同壓力下的膨脹率,以及各深度膨脹土的膨脹量。結閤礦物成分及化學成分,分析鷄街膨脹土的脹縮性等工程特性。對鷄街土層含水率進統計,得齣鷄街地區膨脹土含水率變化麯線,結閤膨脹土變形量進行分析,為膨脹土地區工程建設提供瞭依據。

Accoeding to the drill hole sample and spot testing of Jijie,we have got the swelling coefficient of Jijie expensive soil under different P and the swelling amount of it at different depth.And we have an analysis of the swelling and contraction engineering characteristics of Jijie expansive soil in combination with the mineralogical and chemical composition.We have carried out the statistics of water content of Jijie soil layer,then got the variation curve of water content of Jijie expansive soil and analysed in combination with the deformation amount,which will provide the foundation for the engineering construction in the expansive soil area.
