Investigation of hazard rock fall in Khorramabad- Andimeshk road by WCS method

The connective ways of khorramabad (lorestan state) with the nearest cities are olways influenced by the rock fall which is needed the special attention and the hard working of sponsers. In the research we work on the levels of slope stability of Gavzardeh region in 70 km of Khoramabad in Lorestan. For measuring of rock masses of this area, we use the WCS methode. We searched 5 parametere, such as index of RQD, roughness of discontinuities, filling of discontinuities, spacing of discontinuities and opening of discontinuities which we will explain all of them one by one.
