Evaluating rock masses for dam foundations, especially heterogeneous (flysch), becomes imperative and requires accurate geomechanical classifications. The rocks at the Kanarwe river basin, a proposed site (Goma-Qazan near Khewata, Sura Qalat villages), mainly consist of interlaying massive carbonate Aqra Formation with flysch Tanjero Formation. Therefore, selecting appropriate types is challeng...

the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic stability of theses blocks are investigated by a special finite element program "MAP-73" which its nonlinear algorithm and interface elements formulation are presented.

Dam deformation monitoring can directly identify the safe operation state of a dam in advance, which plays an important role safety management. Three-dimensional (3D) terrestrial laser scanning technology is widely used field due to its fast, complete, and high-density 3D data acquisition capabilities. However, point clouds are characterized by rough surfaces, discrete distributions, affect acc...

The deformation of arch dam during impoundment is critical to evaluate the safety dam, which influenced by many factors that have different action mechanisms. After monitoring data at stages were comprehensively analyzed, a finite element simulation analysis model can consider real temperature, stress and was set up with help method based on whole process effectively separate single caused wate...

The effect of solar radiation on thermal distribution in thin high arch dams is investigated. The differential equation governing thermal behavior of mass concrete in three-dimensional space is solved applying appropriate boundary conditions. Solar radiation is implemented considering the dam face direction relative to the sun, the slop relative to horizon, the region cloud cover, and the surro...

At present, the analysis of monitoring data for stress dam is mostly based on statistical models. However, some arch dams have considerably large error, it hard to build a reasonable statistic model data. In order solve practical application problem project, this paper calculates elastic modulus by using finite element displacement hydraulic component separated from horizontal displacement. The...

Xiaowan Hydropower station’s dam located in south west of China is the second highest arch dam in the world (h = 292 m), its foundation is based on brittle rocks of biotite granite gneiss and amphibolites plagioclase gneiss. A largescale excavation around the foundation of the dam was conducted, near to 90 meters horizontal depth excavation and 130 meters vertical depth excavation, so the found...

In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...
