Research on Application of Dam Curtain Grouting Construction in the Reinforcement of Shangping Reservoir
With the increase of service life and changes in the natural environment,the safety issues of reservoirs are becoming increasingly prominent.A study on the application of curtain grouting construction in the reinforcement of the Shangping reservoir is proposed to the problems of seepage and deformation in the dam.This study first conducts a design of self-defense curtains,and then analyzes the design of curtain grouting and anti-seepage reinforcement.The results show that the permeability of grouting holes and inspection holes in different segments is less than 10Lu,and the permeability meets the design requirements.The seepage flow of the reservoir after grouting is smaller than that of the reservoir before grouting.The reinforcement method proposed in the study can effectively reduce the permeability and seepage flow of reservoirs.
