某换流站地基处理方案研究

为确保工程质量、节省工程投资、保护环境等,该文以某±800 kV换流站地基处理方案研究为例,首先介绍换流站站址的地形和工程地质条件,并分析场地平整后不同区域的挖填方情况,提出适合该换流站地基处理的3种方案,在进行详细的技术经济比较之后推荐干作业旋挖成孔灌注桩方案进行地基处理。

To ensure the quality of the project,save project investment,protect the environment,etc,taking the study of the foundation treatment scheme of a±800 kV converter station as an exemplar,this paper introduces the topography and engineering geological conditions of the converter station site,analyzes the excavation and filling in different areas after site leveling,and puts forward three schemes suitable for the converter station foundation treatment.After a detailed technical and economic comparison,the dry operation rotary drilling cast-in-place pile scheme is recommended for foundation treatment.
