The excavation of the foundation, the process of dam construction and the water level variation in foundation have significant effects on the displacement of the foundation and structure of a sluice dam on deep overburden. A finite element simulation method for the coupling of seepage and deformation during the whole process of the dam construction and operation was proposed to treat the foundation of a dam in Jinsha River. The results show that the foundation settlement caused by the dead weight of the filled concrete body of about 1 m height can be offset by 3 m height groundwater level rising in the foundation during the sluice construction. The change of groundwater level has a significant impact on the displacement increment of sluice dam during the construction period. The coupling simulation of seepage and deformation of the sluice dam in the whole construction and operation process was realized, which has supported the engineering design of the dam foundation treatment.

鉴于深厚覆盖层上闸坝的坝基开挖、闸浇筑和基坑内的水位变化对闸基和闸结构的位移均有显著影响,提出了大坝施工与运行全过程中渗流与变形耦合的有限元仿真方法,并将其应用于金沙江某闸坝的地基处理中。结果表明,闸填筑过程中,基坑地下水位升高3 m,能抵消约1 m高混凝土浇筑自重引起的坝基沉降,地下水位变化对闸坝施工期位移增量有显著影响,实现了施工与运行全过程中闸坝的渗流与变形的耦合仿真,支撑了坝基处理工程设计。

鉴于深厚覆盖层上闸坝的坝基开挖、闸浇筑和基坑内的水位变化对闸基和闸结构的位移均有显著影响,提出了大坝施工与运行全过程中渗流与变形耦合的有限元仿真方法,并将其应用于金沙江某闸坝的地基处理中。结果表明,闸填筑过程中,基坑地下水位升高3 m,能抵消约1 m高混凝土浇筑自重引起的坝基沉降,地下水位变化对闸坝施工期位移增量有显著影响,实现了施工与运行全过程中闸坝的渗流与变形的耦合仿真,支撑了坝基处理工程设计。

The excavation of the foundation, the process of dam construction and the water level variation in foundation have significant effects on the displacement of the foundation and structure of a sluice dam on deep overburden. A finite element simulation method for the coupling of seepage and deformation during the whole process of the dam construction and operation was proposed to treat the foundation of a dam in Jinsha River. The results show that the foundation settlement caused by the dead weight of the filled concrete body of about 1 m height can be offset by 3 m height groundwater level rising in the foundation during the sluice construction. The change of groundwater level has a significant impact on the displacement increment of sluice dam during the construction period. The coupling simulation of seepage and deformation of the sluice dam in the whole construction and operation process was realized, which has supported the engineering design of the dam foundation treatment.
