土工格栅护坡的运用及地基处理方案的选择

The Application of Geogrid Slope Protection and the Selection of Ground Treatment Schemes

结合阳城北500kV变电站的高填方地形、地质条件,采用新型土工格栅护坡与孔内深层强夯法(DDC)灰土桩、灰土垫层法相结合的方案,达到站址稳定,地基不均匀沉降减小的目的,保证变电站的正常运行。

Connecting with the high fill landform and geological conditions of 500 kV substation in the north part of Yangcheng, the scheme of combining the new-type geogrid slope protection, DDC （down-hole dynamic compaction） limesoil pile and lime-soil cushion was adopted for achieving the aims of stabilizing the site of the substation, reducing the uneven subsidence of the foundation and insuring the normal operation of the substation.
