The small crosssection top heading excavation method is adopted in rockburst section of Qamchiq Tunnel on AngrenPop Railway in Uzbekistan, so as to guarantee the construction schedule of rockburst section and reduce the stress releasing strength of surrounding rocks. The abovementioned method can realize the stress releasing and transferring of surrounding rocks at crown top and arch waist, dissipate the stress concentration zone of surrounding rocks, and further reduce the rockburst risk of surrounding rocks. The construction practice shows that the small crosssection top heading excavation method is superior to other methods, such as stress releasing holes and advance heading, in terms of construction efficiency. The results can provide reference for rockburst prevention of similar projects in the future.
