摘要： 介绍了某500 kV变电站工程场地地貌、岩土条件以及水文地质条件，结合原位测试和室内土工试验，得到边坡设计参数；经过计算后确定设计方案为放坡+扶壁式挡土墙支护型式，局部地段采用重力式挡土墙。并对边坡工程的施工和监测进行了简要的介绍，为以后的工程设计提供参考。

Abstract: This paper presents a case study of the geotechnical investigation of a 500 kV electricity transformer substation. The geotechnical and hydrological conditions, especially slope supporting parameters of the site are characterized throughout the insitu and laboratory tests.  The most cost effective retaining structure is predominantly the buttress type with gravity wall at some locations. The construction and monitoring aspects of the supporting structures are also introduced in this paper.
