1Laboratory pull-out tests on fully grouted rock bolts and cable bolts:Results and lessons learned显示文摘Laboratory pull-out tests were conducted on the following rock bolts and cable bolts:steel rebars,smooth steel bars,fiberglass reinforced polymer threaded bolts,flexible cable bolts,IR5/IN special cable bolts and Mini-cage cable bolts.The diameter of the tested bolts was between 16 mm and 26 mm.The bolts were grouted in a sandstone sample using resin or cement grouts.The tests were conducted under either constant radial stiffness or constant confining pressure boundary conditions applied on the outer surface of the rock sample.In most tests,the rate of displacement was about 0.02 mm/s.The tests were performed using a pull-out bench that allows testing a wide range of parameters.This paper provides an extensive database of laboratory pull-out test results and confirms the influence of the confining pressure and the embedment length on the pull-out response(rock bolts and cable bolts).It also highlights the sensitivity of the results to the operating conditions and to the behavior of the sample as a whole,which cannot be neglected when the test results are used to assess the bolt-grout or the grouterock interface.Isabelle Thenevin Laura Blanco-Martín Faouzi Hadj-Hassen Jacques Schleifer Zbigniew Lubosik Aleksander Wrana 2017Journal of Rock Mechanics and Geotechnical Engineering2017,9,5:14
2肉仔鸡吸收不良综合征显示文摘目前,世界范围内的肉鸡生产都把追求高水平的生产性能作为目标,但肉仔鸡吸收不良及饲料(在粪便中)残留(feed passage)却一直是这一目标的障碍。吸收不良从两个方面影响肉仔鸡的生长效率,第一是饲料吸收不充分时,饲料成本因此上升;John Schleifer 吉守一 1996国外畜牧科技1996,23,2:2
