| Abstract: | The rock anchor foundation applications for transmission line in investigation, design, construction and detection were studied. Some technical measures were proposed, such as using high intensity steels and swelled rock anchor. And the hole bottom expanding foundation, the composite foundation and group steels foundation could enlarge the application scope of rock anchor foundation in transmission line, which could provide references for other engineering applications of rock anchor foundation |
