小曼萨河隧道裂缝成因分析与加固

ANALYSIS OF THE CAUSE OF CRACK AND THE STRENGTHENING FOR THE XIAOMANSAHE HIGHWAY TUNNEL

根据现场调查、检测资料和隧道开挖ANSYS仿真模拟，对元（江）磨（黑）高速公路小曼萨河隧道裂缝的形成及产生原因进行了系统的分析，同时提出了加固措施。实践证明，该加固方案是切实可行的，对类似工程加固具有一定的指导意义。

According to the data of investigation and examination at the locate and ANSYS simulations of tunnel excavation, the manifestation and the reason of crack in the Xiaomansahc highway tunnel are systematically analyzed . At the same time, the repair scheme of the crack is drawed out. At tested by practice, the repair scheme is feasible and has actual value for the similar engineering.
