对于位于山前冲洪积倾斜和坡洪积倾斜平原地带,往往由于地势原因,拟建设场地的地层厚度不一致,给大面积强夯地基处理带来一定的困难。为此,以河北省赤城县拟建的某220k V变电站场区为例,针对建设区内地势特征,结合地层厚度分布特性,有针对性地对强夯地基处理方案进了设计,对于降低工程施工成本,缩短施工周期有一定的参考价值。
For the alluvial slopes and slope alluvial plain located in front of the mountain, the thickness of the stratum in the proposed site is often inconsistent due to topographical reasons, which brings some difficulties to the large-area dynamic compaction foundation treatment. In this paper, taking a 220k V substation area planned to be built in Chicheng County, Hebei Province as an example, according to the characteristics of the topography in the construction area and the distribution characteristics of the thickness of the stratum, the ground treatment plan of the dynamic compaction is designed in a targeted way, Construction costs, shorten the construction cycle of a certain reference value.
