摘要

为解决人工管片选型给盾构姿态和成型管片质量带来的隐患，将成熟的人工管片选型经验逻辑和合理简化计算模型根植于管片自动选型决策算法的内核，以影响管片选型的施工参数为研究对象，提出综合考虑盾尾间隙、推进油缸行程差和盾构趋势的管片选型计算方法和决策算法，预先考虑各影响因素实际施工中所有可能出现的取值范围以及不同施工工况下的权重变化。该软件首次针对大直径盾构特点开发8组盾尾间隙和6组油缸行程的算法，借助盾尾间隙智能化测量和监控屏幕参数图像识别技术，实现通用型管片选型参数智能化采集。在盾构隧道施工中配套使用，经多个项目现场验证和应用，管片选型算法合理，契合现场施工要求，起到规范或代替人工管片选型施工、保障成型隧道质量和盾构掘进姿态的作用。

Abstract

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 decisionmaking 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 largediameter 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.
