Numerical Modelling of a Diaphragm wall Process in Karolinka Dam
Keywords:
Karolinka dam, Diaphragm wall, Finite Element Method, Displacement analysis, Safety factor, Sensitivity analysisAbstract
This study focuses on the possibility of numerical modelling of the most important sealing technology, diaphragm walls as the most major popular reliable option when it comes to engineering construction rehabilitation. It is included how to carry out, interaction with adjacent soil, safety factor evaluation associated with the state of the dam body and foundation; before, during, and after reconstruction, changing of pore water pressure with the time, settlement of dam, cement shrinkage, and sensitivity analysis. This modelling was conducted with the finite element method based on software Plaxis 3D. Diaphragm wall has been used in Karolinka dam for reducing seepage through its body. The results are concluded that the highest value of the displacement during the reconstruction process is the horizontal displacement due to water load and pore water pressure variations with the time. Safety factor is highly influenced by the variation of water level in the reservoir, elasticity modulus, and cohesion of the soils.
