Abstract:

The rational setting of shield tunneling parameters is the basis guarantee to the construction quality and safety of shield tunnel. In order to realize the accurate setting of tunneling parameters, the Kmeans clustering algorithm is combined with the empirical formula setting method based on the theory of typical engineering analogy setting, and the shield advancing parameters analog setting method (SAPAS) is proposed to realize automatic extraction and matching of tunneling parameters under typical engineering conditions. Comparing with the traditional empirical formula method, SAPAS improves the practical application effect of empirical formula, and can set parameters more accurately, and it is beneficial to improve the construction quality and safety. By adopting the method in some engineering practices of Shanghai rail transit, good results have been obtained.
