摘要:
［目的］为解决人工进行标准环+转弯环(双面楔形)盾构管片排版和选点中存在的主观性强、计算繁琐、重复工作量大等问题，特对其进行算法研究，以解决实际工程问题。［方法］开发了标准环+转弯环管片自动排版、拼装选型及预测算法软件。基于成熟施工经验，依据隧道线形和管片转角计算管片排版计划，实现了管片排版的自动化计算。提出了综合考虑隧道线形、盾尾间隙、推进油缸行程和盾构机趋势的标准环+转弯环管片选型计算方法和决策算法，实现了管片自动拼装选点。在此基础上，通过建立盾构姿态变化与盾尾间隙和油缸行程变化量的关系式，实现了未来2环标准环+转弯环管片拼装点位和管片型号的预测。［结果及结论］研究成果在广州地铁12号线成功应用，显著提升了现场标准环+转弯环管片排版、选型的工作效率，降低了人力成本，并优化了盾构隧道施工工序。
Abstracts:
［Objective］ To address the challenges associated with the manual layout and point selection of S+T (standard rings+turning rings (double-sided wedges)) in shield tunnel segments, including high subjectivity, complex calculations, and heavy repetitive workload, a research is carried out focusing on algorithm development to resolve practical engineering issues. ［Method］ An automatic layout, assembly selection, prediction algorithm and software are developed for S+T in tunnel segments. Referring to mature construction experience, segment layout plan is calculated based on tunnel alignment and segment turning angles, and segment layout calculation automation is achieved. The calculation and decision-making methods of S+T segment types are proposed with comprehensive consideration of tunnel alignment, shield tail clearance, hydraulic cylinder stroke, and shield machine trends, enabling the automatic selection and assembly of segment points. Furthermore, by establishing a relationship between shield posture changes and variations in shield tail clearance and cylinder stroke, the algorithm can predict the S+T assembly points and segment types for the two future rings. ［Result & Conclusion］ The research results are successfully applied to Guangzhou Metro Line 12, significantly improving the efficiency of on-site S+T layout and selection, reducing labor costs, and optimizing the shield tunnel construction process.
