we use high-resolution electrical resistivity imaging to delineate the geometry of the landslide and discontinuity surface between slide mass and bedrock in roudbar region, ghazvin-rasht-anzali railway (the tunnel no. 2 at km. 108+825). the roudbar region characterized by high geological hazard and shows a complete panorama of mass movements. in this area, different landslide types predisposed ...

In the process of tunnel construction, water inrush disaster is one main engineering geological disasters. karst strata, different types water-bearing structures or bodies develop and occur in soluble rock layer, excavation easily forms new drainage channels, resulting tunnel. Based on project Huali Highway Banyanzi Tunnel, this paper studies characteristics, mechanism, treatment measures Accor...

Engineering structures are of great importance in the comfort and safe travel people who prefer highway existing transportation networks. Highway tunnels one most important engineering that easily overcome problems. This study investigates geological geotechnical Kırık tunnel on Erzurum-Rize route, makes rock mass classification required for excavation according to New Austrian Tunneling Method...

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 lo...

One of the common and at same time most difficult problems that developers may face is unstable soil layer base a future building. This paper describes construction on weak, subsidence heaving soils in engineering geological conditions Kursk city. Real problem property safety shown with example one demanding geomorphological lithological urban areas. The offers description geologic hydrogeologi...
