Segment type selection method and device

Abstract

The invention discloses a shield tunnel segment type selection method and device, and the device comprises a three-dimensional modeling module which is used for building a three-dimensional model of a segment and calculating the difference adjustment result of the segment at each splicing point; the monitoring and analyzing module can be connected into a shield equipment guiding system and shield tail gap measuring equipment, import of a shield tail gap measuring result is completed, and a shield tail gap predicted value after point location selection is calculated in combination with the tunneling posture; the model selection confirmation module can input a shield tail gap target value, evaluate and compare a shield tail gap predicted value calculation result, and complete duct piece model selection and splicing point selection; and the result output module can perform three-dimensional display on the duct piece information subjected to model selection confirmation, generate a result list of model selection of each ring of duct pieces, and generate an overall three-dimensional model of the tunnel structure according to the actual progress. According to the method, the standard method of duct piece type selection is standardized, the splicing quality of the shield tunnel duct pieces is improved, and the construction safety and efficiency are further guaranteed.
