摘　　要：2005年在华北地区的岩石锚杆基础试验与应用研究表明,在华北地区典型的强风化岩石地基中,采用岩石锚杆基础是可行的。岩石锚杆基础应用于山区线路工程中,能充分发挥原状岩体的力学性能,具有良好抗拔性,工程中减少了混凝土用量,减少了施工运输量,避免了大开挖,减小了对植被的破坏,大大节约了直接和间接费用。在浑源—霸洲等线路工程中岩石锚杆基础的运行状况良好。The experiment and application studies of rock bolt foundation in North China area in 2005 indicated that it is feasible to use rock bolt foundation in North China＇s strong weathered rock foundations. When used in mountain area line construction, rock bolt foundation can take advantage of the mechanical properties of original rocks, which improves the anti-uplifting capability, reduces concrete consumptions, decreases the volume of transportation, avoids large digging, minimizes damage to vegetation, and saves direct and indirect costs significantly.hs applications in several line constructions, such as Hunyuan-Bazhou line, turn out to be successful.
