ABSTRACT

In order to improve the service life of reservoirs and reduce the risks associated with their use in water conservancy projects, this study focuses on the curtain grouting reinforcement construction technology applied in the construction of reservoirs in a specific region. The physical and mechanical properties of the geological conditions of the dam foundation site of the reservoir are analyzed, taking into account factors such as construction period, cost, and desired treatment effects. The curtain grouting reinforcement technology is adopted, which involves five steps: drilling, flushing, hydraulic testing, grouting and sealing, and special case handling, to reinforce the leakage of the reservoir. The reliability of the reinforced anti-seepage measures is analyzed using finite element models. The experimental results show that the construction results of each step meet the construction standards. The permeability coefficients at different locations are within the allowable range of 8.9×10-6cm/s, and the results of the specific discharge of the soil layers are smaller than the allowable decrease in specific discharge. The construction effect meets the reinforcement requirements.
