A sodium silicate-based chemical grout was used in the Karkheh dam site in order to examine the performance of the chemical grouting technique for stabilization of the dam's filter material. Karkheh, an embankment dam with the reservoir capacity of about 7.4 billion cubic meter at the maximum water level, is the largest dam in Iran. The grouting works performed at the dam site, were part of the...

Abstract One of the most important issues in earth dams is control rate seepage from foundation and dam bodies. Due to site dams, increase creep length reduce seepage, there are several methods for sealing reservoir that construction cut-off wall under clay core one effective methods. In this study, pore water pressure Eyvashan dam, comparison instrument results with numerical analysis and, fin...

The ground in Saemangeum has a high water level and is mostly composed of silty soil sand, which makes it susceptible to liquefaction seepage effects. To investigate the seismic response geotextile tube-reinforced embankment shallow foundations laid on liquefiable soil, simple spring type shaking table apparatus was developed. variation acceleration shear stress-strain relationship were investi...

In recent years, non-water reaction polymer grouting is a new technology for anti-seepage and reinforcement that has been widely employed in projects. However, there little research on the consequence of defective cutoff walls affecting seepage safety earth dams. To analyze influence number, location, randomness defects wall characteristics dam, three-dimensional finite element model typical da...

Seepage is the primary cause of dam failures. Conducting regular seepage analysis for dams can effectively prevent accidents from occurring. Accurate and rapid determination parameters a prerequisite calculation in hydraulic engineering. The Whale Optimization Algorithm (WOA) was combined with Support Vector Regression (SVR) to invert conductivity. good point set initialization method, cosine-b...

Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. Recently, the technique of Interferometric Synthetic Aperture Radar (InSAR) has proved its potential to measure ground and structural deformation. This geodetic method represents a cost...
