Abstract：Based on the discussion on some problems existing in the tunnel design and construction，a new method to build an automatic analysis platform for tunnels is proposed，which is based upon lots of numerical test results，expert experiences and the powerful artificial neural network method. In the platform，many factors impacting on the stress and deformation fields of the surrounding rock masses can be considered，such as the size of underground tunnels，the overburden，the mechanical parameters of rock masses，the initial stress and the main fault nearby，etc.. The proposed numerical platform has been compared with large scale numerical analysis and field measurement，with the error of less than 10%–20%.
