本文采用步步递推的方式,回归建立预报数模,并应用该数模预算求得隧拱沉降预报值,进而以沉降预报值为参照,成功实施隧道施工的安全质量监控。文中所述方法,对隧道工程极具实用价值,对同类工程亦具参考意义。 In this paper, the method of step by step recursion is used to establish the forecasting numerical model by regression, and the prediction value of tunneling settlement is obtained by using the numerical model budget. The safety quality monitoring of tunneling construction is successfully implemented by reference to the settlement forecast value. The method described in this article is of great practical value to tunneling projects and also of reference to similar projects.
