Mature
artificial segment selection experience logic and reasonably simplified
computation model are rooted in the segment automatic selection decision
algorithm′s kernel to avoid the hidden dangers of manual segment ring
selection to the posture of a shield and the quality of formed segments.
Additionally, the construction parameters influencing ring selection are taken
as the study object, and a complete analysis of shield tail clearance, propulsion
cylinder stroke difference, and shield trend based on the ring selection
computation approach and decisionmaking algorithm is
proposed. Furthermore, all the feasible value ranges of each influencing factor
in the actual construction and their weight change under various construction
conditions are considered in advance. The approach is the first algorithm
developed for eight groups of shield tail clearances and six groups of cylinder
strokes based on the characteristics of largediameter
shields, realizing an intelligent selection of universal segment parameters
using an intelligent shield tail gap measuring and monitoring screen parameter
image recognition module. The method′s field applicable
results in several projects indicate that the segment selection algorithm that
meets field operation requirements is reasonable, can standardize or replace
manual segment ring selection and ensure the
complete quality of tunnel and shield tunneling posture.
