摘要：The urban rail transit shield will have a bad influence on the railway's safe operation when it tunnels under existing railways. Main measures to avoid risks include reasonable analysis of the influence of tunneling under existing railway subgrade, design of effective construction schemes and reinforcement of protection of existing railways. According to the case of engineering of Wuhan Metro Line 7 under the existing Wuhan-Guangzhou Passenger Railway, the influence of the metro tunneling project on the settlement of Wuhan-Guangzhou Passenger Railway subgrade is analyzed. In addition, precautions for the tunneling project and protection measures for the existing railways are proposed herein.
