TY - JOUR T1 - Designation of Computer Software For Assesment of Rock Mass Parameters TT - معرفی برنامه رایانه‌ای ویژه جهت تعیین پارامترهای مهندسی توده‌های سنگی JF - jeg JO - jeg VL - 1 IS - 3 UR - http://jeg.khu.ac.ir/article-1-312-en.html Y1 - 2004 SP - 241 EP - 254 N2 - (paper pages241-254) For the analysis of the stability of underground opening or rock slopes, it is essential attent to rock mass parameters. To assesment of these parameters, Hock-Brown and or Mohr- Columb criteria has been used. In this paper, a software has been presented to calculate rock mass parameters on the base of abovementioned criteria. Input data of this softwear are underground opening deep or failur surface of slopes, unite weight of rock mass, GSI(Geological Strength Index), sigci (uniaxial compressive strength of intact rock) and mi (costant of Hoek-Brown for intact rock). The out put data are 12 cases, that use for the analysis of the stability of underground opening or slopes. M3 ER -
