A three-dimensional analytical solution to the arching effect in inclined backfilled stopes

Geomechanics and Geoengineering, 2019
The stress state in backfilled mine stopes is an important issue to assess the behavior of the interaction between the backfill and the surroundings or barricades. Most previous arching analyses have considered only the vertical backfilled stopes in both

Arching effects behind a soldier pile wall

Computers and Geotechnics, 2001
Abstract A wall consisting of anchored steel piles with horizontal timber laggings was selected to support a 16 m deep excavation with a length of more than three kilometres near Cologne in Germany. Vertical holes were bored on the wall line, at 4 m centres, and steel piles were placed within these holes.

Effects of lingual arch used as space maintainer on mandibular arch dimension: A systematic review

American Journal of Orthodontics and Dentofacial Orthopedics, 2010
The aim of this systematic review was to examine the effects of a lingual arch on mandibular arch dimensions when it is used as a space maintainer.PubMed, Medline, Lilacs, Cochrane Central, and Cochrane Database of Systematic Reviews were surveyed for articles published between January 1980 and January 2009.

[Clinical effect of removable lingual arch plus auxiliary spring for dental arch expansion].

Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2010
Observe the clinical effect of removable lingual arch plus auxiliary spring for convenient dental (especially mandibular) arch expansion.Seventeen patients with dental arch constriction complicated by mild dental crowding were enrolled in this study, including 9 requiring maxillary arch expansion and 8 necessitating mandibular expansion.

Arch effect in high isostatic pressure compacts

Journal of the European Ceramic Society, 1999
Abstract Arch effect arising under isostatic pressing of the cylindrical or spherical powder compacts is commonly known to cause a loosely packed interior region inside the pressings. Using the results of the shell stability theory it is shown that under definite compact's geometry and powder characteristics, arch effect can involve latent cracking ...
