Abstract: In the context of the profound integration of information technology and engineering construction,the process of tunnel construction is undergoing a gradual intelligent transformation.However,the current method of tunnel lining construction relies heavily on manual experience to adjust the tunnel lining trolley position,and the problem of over-pouring lining concrete is prominent.In light of the challenges encountered in the field of tunnel lining construction,this paper puts forward a multi-model combination method that integrates the lining model and the tunnel lining cart model.The proposed approach entails the construction of a lining pouring volume estimation model,and the execution of precise simulation and quantitative analysis of the tunnel lining construction process.The validation experiment employs the GTFS project as a case study,utilizing point cloud data from various construction periods of the tunnel lining.The experiment then simulates the lining pouring process for the designated project,integrating the design data of the lining cart.The results show that the estimation of lining pouring volume meets the demand of tunnel construction.The approach provides a foundation for decision-making,facilitating the adjustment of the lining trolley position and the estimation of the concrete pouring volume.The method effectively supports the digital simulation of tunnel lining construction processes and the rational formulation of concrete pouring plans for the tunnel lining.
