压力分散型锚索与拉力集中型锚索抗振性能研究
Research on anti-vibration ability of pressure dispersed anchor cable and tension concentrated anchor cable
摘要
Abstract
In the engineering of Passenger Dedicated Line from Beijing to Shijiazhuang, a 5 km long tunnel parallel to the existing Jing-Guang railway line with a distance ranging from 5 m to 20 m was built with open cut method. A testing length supported with pressure dispersed anchor cables was designed and constructed to compared with the commonly used tension concentrated anchor cables on both dynamic response and anchorage effect. Based on data measured for half a year on site, the research on performance and character of these two kinds of anchor cables was made. It is proved that the anti-vibration ability of the pressure dispersed anchor cable is 5 times stronger than the tension concentrated anchor cable. Furthermore, the former has advantages of shorter stress transfer time, stable anti-vitration of long period, less loss of prestress.关键词
