That’s not enough laboratory tests that was done on intact samples can’t preparing index of rock mass properties in the large scale. On the other hand, doing experience tests aren’t accepted for the assessment insitu rock mass strength, especially in the feasibility studies. While, it was happen slip surfaces in rock mass the best method to estimation of rock mass strength values is previous slides back analysis. Conventional method is used for this problem solving, Mohr-Coulomb and Hoek-Brown failure criteria. In this method essential rock mass parameters are determined with a lot method such as, engineering rock mass classification. According to the large changes of Sungun copper mine rock mass properties, for determination of mine slope material cohesion strength and internal friction angle uncertainties, effective parameters on rock mass properties are supposed as random variables statement finally for each run of drilling process rock mass classification was done. In this study, rock mass classification of Sungun copper mine slopes was done by using RMR and GSI methods. Confidence level of geotechnical parameters are determined 90% approximately. Then Monte-Carlo simulation method (MCSM) is used to produce the probability density function of mentioned random variables(C, ϕ).

There are many methods to estimate the magnitude of the flood. One of the most recent methods is using Artificial Neural Networks. In this paper, a Neural-Wavelet Network (NWN) using wavelet theory and Artificial Neural Networks (ANN) for Halil river basin in SE of Iran is reported. Furthermore, a new rainfall-runoff pattern is reported. This pattern ncludes the classification of data in the harmonic data groups and the use of Neural-Wavelet Network.The introduced pattern is analyzed by the NWN model and results are prepared with Artificial Neural Networks Back propagation and Radial Base Function (RBF) model results. Halil basin was selected to used for our model. The calculations of the R-square and root mean square error (RMSE) can control the accuracy of our computations.

Creep in the coastal sediments may happen by the virtue of existing cracks and fissures, unnatural movement and/or loss of the earth tolerance. This phenomenon in sandy areas may happen by increasing the pressure of gang ionic water and is called liquefaction. Studying the laboratory sample shows that the capability of liquefaction of sandy deposits can be decrease by flattening the land. One of the ways to improve the soil to increase the tolerance while applying dynamic loads is dynamic compaction. The design and usage of dynamic compaction usually depend on experiment. Dynamic compaction is an active design which needs a revision and method reformation in progress according to the reaction of the earth against the hit. In 12 parts of ship manufacturing and repairing factories bed in the Iran ship building and offshore industries complex co. located in 40km away in the west of Bandar Abbas, Dynamic compaction has been used to prevent liquefaction phenomenon. While performing of water in pressing step are happened that the following approaches are suggested: 1- To empty the water of sinkholes by a pump, 2- To perform dynamic compaction in two steps with regarding the adequate time between the steps of applying hits. and 3-Sludge taking in the surrounding areas and using large grain mixture and finally if needed to do deep drainage in a large area.}, Keywords = {are suggested 1- To empty the water of sinkholes ,}, volume = {2}, Number = {2}, pages = {473-492}, publisher = {Kharazmi university}, url = {http://jeg.khu.ac.ir/article-1-326-en.html}, eprint = {http://jeg.khu.ac.ir/article-1-326-en.pdf}, journal = {Journal of Engineering Geology}, issn = {2228-6837}, eissn = {2981-1600}, year = {2008} } @article{ author = {}, title = {Evaluation of Engineering Geological Properties of Chapar-abad Alluvial Dam Foundation: Revisiting Sealing Problems}, abstract ={Considering the seepage and choosing an efficient sealing method is very important in dam projects. This issue has a close relationship with engineering geological properties of the dam site. Chapar-abad dam is an inhomogeneous earth-fill dam of 44.5 meters height, crest length about 427 meters and a reservoir capacity of 127 million cubic meters. The dam project is under construction and is located about 75 Km southeast of Uromieh city, in West Azerbaijan Province. The foundation materials include 60 meters of alluvium deposits overburden bedrock layers of carbonate units. The abutments consist of carbonate and schistose layers of Precambrian age. In order to control the seepage through the Alluvial foundation, several sealing methods were considered. The methods include grout curtain, cutoff-wall, impervious blanket, open compacted trenches, and the use of geosynthetics are evaluated. In this research using a finite element package named Plaxis was utilized. The results indicate that although the cutoff-wall is usually considered as the best method for this type of geological condition, but due to the instability of granular soils and the possibility of liquefaction capability, the grout curtain is proposed as to be an efficient method.}, Keywords = {}, volume = {2}, Number = {1}, pages = {281-302}, publisher = {Kharazmi university}, url = {http://jeg.khu.ac.ir/article-1-2562-en.html}, eprint = {http://jeg.khu.ac.ir/article-1-2562-en.pdf}, journal = {Journal of Engineering Geology}, issn = {2228-6837}, eissn = {2981-1600}, year = {2007} } @article{ author = {}, title = {Inspection of encountered water in power tunnel of Saymareh dam site, Ilam}, abstract ={Saymareh dam and hydro-power plant are under construction on Saymareh River in Ravandi anticline, Ilam province.
