Diseases Analysis of Unsymmetrical Loading Tunnel and Study of Its Treatments
According to the tunnel defects that occurred during construction of a certain unsymmetrical loading tunnel in Ya-Lu high-way, the main reasons of the defects occurrence are analyzed by from three aspects: the terrain, the geologic agent, the climatic factor and the construction factor. Then the remediation plan and construction process of the defects at the location of unsymmetrical loading tunnel are introduced. Thirdly, by ANSYS software, the excavation process at the location of unsymmetrical loading is simulated, and the changes of stress field in the excavation process is also reflected, then compared to the position of occurred defects in order to verified the reasonableness of the disease treatments method. At last, the danger parts of unsymmetrical loading tunnel excavation and the treatments of defects are summarized to offer reference for workers of the tunnel.
