Abstract: The paper analyzed on the behavior of surface deformation and inner deformation of Shanxi fock-fill dam. By comparing with similar projects, the change laws of dam settlement and horizontal displacement were summarized. Further, the assessment of construction quality and operation performance was carried out. 

Key words: Shanxi hydropower station, rock-fill dam, deformation, behavior analysis

摘要： 对珊溪大坝堆石体表面和内部变形性态进行了详尽的分析，与类似工程进行了比较，掌握了大坝沉降和水平位移的变化规律和分布特点，进而对大坝填筑施工质量及运行性态进行评价。
