Pull Out Test Apparatus For Soil Nail Ground AnchorApplications and FeaturesJW series pull test instrument for bolt is mainly used in anchoring force detection for anchor rod, anchor rope, steel bar, expansion bolts. It is the necessary instruments for bolt construction engineeri...
soil nail pull out testingbond stressIn order to evaluate the ultimate bond stress used in modelling soil nail behaviour for lateral support, soil nail pull out tests are conducted on the site. In the analysis of the test results it is assumed that the free length given to the test nail ...
Laboratory soil nail pullout tests were carried out on a completely decomposed granite (CDG) soil in a nearly saturated condition under a combination of different grouting pressures and overburden stresses. In addition, a total of 8 pullout tests were conducted in a slop...
Soil-Nail Pullout Interaction in Loose Fill Materials A laboratory study was conducted to investigate the behavior of soil nails embedded in loosely compacted sandy fills. By varying the overburden pressure, t... B Pradhan,LG Tham,ZQ Yue,... - 《International Journal of Geomechanics》 被引量:...
1) Pull-out test 抗拔试验 1. Then the complete load-displacement curves of the rock anchors are obtained by pull-out tests in laboratory. 普通预应力锚索的常见破坏模式是钢绞线与注浆体脱黏,为防止该类破坏模式的发生并增强内锚固段的锚固能力,将结构工程中的压花锚引入到岩土锚固工程中并进行较大...
