Proceedings of the conference on Recent Advances in Rock Engineering (RARE 2016)
We are pleased to bring out the proceedings of the technical papers accepted inthe International Conference on Recent Advances in Rock Engineering, RARE-2016, (16-18 November, 2016), Bengaluru, India.
The Conference is being organized in the backdrop of increasing problems being faced by design and practising engineers during construction of excavations in rock in difficult ground conditions, urban setting, proximal to critical structures, and environmental issues. Several techniques and approaches have been developed and tried to address the problems. Detailed and accurate field information is essential for estimating reliable design parameters under such circumstances, strata monitoring plays a critical role in correcting and calibrating the models. Recent trends in instrumentation, particularly remote and smart monitoring with diagnostic alert features, have added an important dimension in the design and development of rock engineering practices.
Sharing their hard earned experiences on the above issues, several authors have painstakingly prepared the technical papers for presentation in the RARE 2016 Conference. The level of interest in the main theme of the Conference (advances in rock engineering), and the specialized theme (instrumentation and field measurements), can be gauged from the number and quality of papers received.
The papers cover the entire gamut of rock engineering, with emphasis on recent trends in specific areas, and particularly case studies and experiences of the authors. It is seen from the submissions that 3-D mapping and use of GIS tools are being resorted to for more accurate rock mass characterization. Considerable work has been done for landslidehazard zonation and providing stabilization measures, and much more is needed in developing timely warning systems.A strong need is felt for development of methods for measurement of stresses at depth, and suitable equipment is being developed for this. While micro-seismic monitoring systems have been established for recognizing failures in rock in regional-scale, wire-less remote monitoring systems are still being developed for local-area monitoring. Ground Penetration Radar is emerging as an important tool for probing ahead or for identifyingsub-surface features. Though a number of numerical modelling software have become popular for estimating the stresses and deformations around openings in rock, new software is still being developed for specific cases using the Finite Element Method. While controlled blasting and delay detonators have taken the centre stage in the excavation techniques, the problem of vibration management is the main issue in case of opencast mining.
With papers distributed into appropriate Technical Sessions, these Proceedings provide a record of the authors’ experiences in the field, the present status of the subject and the future directions.We profusely thank the authors for contributing their papers to the Conference. The Review Committee have toiled hard to bring the papers into a uniform format.We also acknowledge the generous help and support from the various Sponsors. We hope this volume will provide an important source of reference for the present state-of-art, emerging trends and case studies in the area of rock mechanics and rock engineering.
