Study on the Slope Bolt Support Design Based on GIS
As the main means of monitoring and early warning of geological disaster, the slope stability analysis is an important part of the geological disaster prevention project. GIS plays an important role in the evaluation of slope stability due to its powerful functions for data processing and spatial analysis. This article discusses the key technology of GIS applied in the slope bolt support design...
متن کاملAnalytical Design of Rock - Bolt Systems
1.INTRODUCTION Some forty years ago, most opening supports and reinforcements were designed using empirical rules defining ground loads acting on the supporting structures. This approach is still popular and interest in it has been renewed by the use of rock mass classification systems (Barton et al. 1974, Bieniawski, 1974,1976,1989). Correlations between rock mass conditions and the type of su...

15 صفحه اولEffect of bolt rib spacing on load transfer mechanism
Rock bolting has firmly used as the coal mine roof reinforcement in underground coal mine. The bolting effect of fully grouted rebar bolt is closely related to the bolt surface profile. This paper provides an experimental study to confirm that bolt rib internal length has great influence on bolting effect. Pull-out tests were conducted using rebar bolt with different rib spacings of 12, 24, 36 ...
