Stress Measurement in Rock Mass
Understanding and estimating the rock stress state has become increasingly important as nowadays numerical models are mainly used as rock engineering design tool. The objective in determining rock stresses may, in many cases, be seen as an interactive process. The type of data needed may change, depending on at what stage an underground project is in. Further more, preliminary measurements may ...
متن کاملEffects of statistical distribution of joint trace length on the stability of tunnel excavated in jointed rock mass
The rock masses in a construction site of underground cavern are generally not continuous, due to the presence of discontinuities, such as bedding, joints, faults, and fractures. The performance of an underground cavern is principally ruled by the mechanical behaviors of the discontinuities in the vicinity of the cavern. During underground excavation, many surrounding rock failures have close r...

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولDynamic Optimization Research on the Section Morphology of Large-span Tunnels in Shallow Rock Mass
The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...
متن کاملSensitivity Analysis of Stress and Cracking in Rock Mass Blasting using Numerical Modelling
Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...
