... Abstract Rockfall phenomenon is a common event in mountainous areas and presents a serious risk to the nearby buildings or infrastructure. Different protection measures may be taken depending on the site conditions. A reinforced soil bund can be effective in stopping blocks with relatively...

... for seismic design of slope engineering and Micro-pile retaining structure The results show that as a flexible supporting structure, Micro-piles can play a good supporting effect in the reinforcement process of soil slope and effectively prevent the possibility of brittle failure. The main frequency band...

... important from safety point of view, but its construction time directly affects the production schedule of the mine. Construction of barricades using steel fiber reinforced shotcrete (SFRS) spray has gained popularity these days due to its faster construction time and reliable strength against a designed...

... increases with the increase of the number of impacts, and the larger the dry density, the greater the cumulative energy dissipation density. According to the energy ratio analysis, only about 28% of the energy is used for the reinforcement of the specimen, and most of the energy is in the form...

... Abstract The article is devoted to one of the most effective and promising methods for improving the structural properties of soils–the method of "Geocomposite". The method is based on the compaction and reinforcement of the soil through the injection of mortar under high pressure, as a result...

... on the bridge superstructure, its supports and therefore also on its infrastructure. In 2012, it was decided to intervene the Antahuacana bridge and carry out the design and construction of the arch type reinforcement. On Cochabamba side a surficial foundation was used. On Santa Cruz side a deep foundation...

... in the infracycle method after 25m of the development advance. On the other hand, the incycle method, for each blast with 4m advance, the application of this support is executed after scalling and loading the material. Afterwards, rebars are installed to serve as reinforcement to the rock mass. In order to better...

... deformation included; increase of ground support and reinforcement; change of footwall drive orientation; and use of the Rock Quality Designation (RQD) and Q' Classification systems during the design phase to evaluate ground conditions. Current mining areas have performed well such that there was need...

... Abstract Deforming ground support and reinforcement is a common occurrence in underground mining. It is the role of the Geotechnical Engineer to manage these conditions, ensuring all accessible areas are considered a safe workplace. Presented is a method utilising 3D mobile laser scanning...

... Abstract Fiber reinforced shotcrete has been used as primary surface rock support, providing the necessary post-crack performance and strain capacity. Both polypropylene and steel fibers have been added on the mix composition in order to achieve the necessary deformation capacity of the fiber...

.... Singh SHEAR STREGTH ENHANCEMENT OF ROCK MASS DUE TO PASSIVE ROCK BOLTS ABSTRACT Rock bolts have been used since long to enhance the shear strength response of jointed rocks in civil and mining engineering structures. However, the assessment of strength response of a rock mass reinforced with rock bolts...

... Abstract In this paper, the compressive strength and failure patterns of reinforced cemented paste backfill (CPB) were studied aiming to promote the stability of backfilled stopes. The concept of ductile backfill was proposed and a series of unconfined compression tests were carried out...

... ABSTRACT The structural design of permanent reinforced concrete linings of tunnels involves significant uncertainties, principally related to the simplistic representation of the concrete structure interaction with the surrounding geological medium and the inherent limitations pertaining...

... facilities with specific focus on key design aspects of the larger research caverns. The scale and sensitivity of this new generation of experiments will place demanding performance requirements on cavern excavation, reinforcement, and liner systems. In particular, proposals for a new neutrino experiment...

The results of the indoor wind-tunnel test discovered that the anti-wind erosion intensity of the samples reinforced with more than 5% of PS enhances 6∼10 times. According to the result of the field wind erosion test, the wall...
