In order to study on the anchoring mechanism of the recoverable anchors,the p-s curves are obtained based on the pullout tests of the anchors with various lengths. The test results indicate that the recoverable anchor is a compression anchor and has good mechanical properties,high bearing capacit...
The anchors injected in mortar joints are shown to have much greater pull-out capacity than that found for anchors in bricks. Passing from 90 to 160mm of embedment depth, a minimum increase by 40% of pull-out strength is observed. The most common failure modes are the sliding failure, ...
anchors.The ultimate pullout capacity of different prestressed anchors are compared.The pratical free end elongation and theoretical elongation of anchors are compared and analyzed.The factors which affects tension deformation and damage of prestressed anchors are discussed combining with the test process ...

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...
1)pull-out test拔出试验 1.The relation between bond and slip of CFRP tendons and concrete structure were investigated and the bond destruction mechanism was analized by pull-out test.通过拔出试验,研究了碳纤维筋与混凝土结构的粘结与滑移关系,分析了粘结破坏的机理。 2.In this paper,the bond streng...
The Sanshandao gold mine is developed near the sea and has high-chloride ion content in the groundwater, resulting in serious corrosion of metal anchors and difficulty in maintaining metal anchors. T...
Design of a pullout machine for testing of concrete and analysis of the pullout resistance of metal anchors embedded in concrete... G Vall Giménez - 《Universitat Politècnica De Catalunya》 被引量: 0发表: 2014年 PULL-OUT TEST OF ANCHOR BOLT FOR FASTENING LEAD DAMPER TO CONCRETE FOUNDATION...
Moreover, a comparison of rotating anchors located near the grouting line indicated that the closer the rotation is to the grouting, the greater will be the improvement in the pull-out capacity. This is a preview of subscription content, log in via an institution to check access. Similar ...
In order to study the value of the ultimate pull-out capacity and effective anchorage length of anti-floating anchors in the western part of Liaoning Province,field pull-out test of anti-floating anchors was carried out on the background of anti-floating anchors in Yulong Times Square in Fuxin...
