Abstract
Masjed-e-Soleiman Dam and Hydroelectric Power plant (170 high rock fill dam with capacity of 2000 MW) is located about 25 Km. to the north east of Masjed-e-Soleiman (Southwestern Iran) on Karun river. The powerhouse cavern is an underground structure, consisting of eight 250 MW power units (4 units each for phase 1 and extension phase). Overburden of powerhouse is 250-320 meters. The first step of project (that is a Dam with supply 1000 MW electricity), has been completed recently. In order to ensure the stability of roof of the extension p.h. cavern, dywidag brand monobars (15 or 20 m. long) with working load of 624 KN have been used. In this paper, the geological condition , rock support measures and the method statement of opening and sequences of excavation for the extension powerhouse cavern, analysis the impact of installation of monobars on cavern roof stability (on the basis of the instrumentation results) have been discussed briefly.
