中文摘要：

以四川地区典型地形地质条件下,某变电站场地沉降及挡墙变形为例,分析其变形特征及主要原因,并提出合理的工程治理措施,降低对变电站正常运行的威胁。同时分析得出回填土沉降是变电站土建工程问题的主要诱发因素,施工过程中应严格控制回填土压实质量。该分析成果可以为电力工程建设提供参考价值。

英文摘要：

Taking the ground sedimentation and the deformation of retaining wall in a substation as an example under the condition of typical terrain and geology in Sichuan area. The deformation characteristics and the main reasons were analyzed. And put forward reasonable engineering control measures to reduce threat to the normal operation of substation. At the same time, it was concluded that the settlement of the backfill soil was the main cause of the problems in the substation civil engineering, and the backfill compaction quality which should be strictly controlled in construction process. The results of the analysis could provide reference value for the power engineering construction.
