| Abstract: | The construction of shallow buried tunnel under unsymmetrical pressure is difficult for the complexity of it＇s construction and uneveness of stress distribution of surrounding rock. In order to ensure the construction period and construction safety, pre-reinforcement technology of surrounding rock in entrance, step method and advanced strengthening technology of surrounding rock are used. |
