摘要:

依托北京市东六环改造项目中京哈高速—潞苑北大街标段大直径泥水盾构隧道工程,结合地应力提取与掘进断面地层信息编码的地质数据处理方法,建立考虑地质条件的盾构参数智能预测模型,提出包含数据获取、数据预处理、数据分解、智能预测模型构建、模型训练与测试、结果评价与分析的一套智能预测分析方法,并对依托工程的盾构掘进参数进行了预测分析。分析结果表明在考虑地质条件后,盾构推力与刀盘扭矩的预测精度分别提高了38.53%与44.86%,保证了后续盾构掘进的施工安全。

Abstract:

An intelligent prediction model for shield tunneling parameters accounting for geological conditions is presented by employing a geological data processing technique which integrates in-situ stress extraction and tunneling section stratum information coding. The method encompasses data acquisition, preprocessing and decomposition, and model construction, training and testing, as well as result evaluation and analysis. The model is applied to predict the shield parameters for the large-diameter slurry shield tunnel project of the Luyuan North Street section on the Beijing-Harbin Expressway within the Beijing East Sixth Ring Road reconstruction project. Findings reveal that accounting for geological conditions enhances the prediction accuracy of shield thrust and cutter-head torque by 38.53% and 44.86%, respectively. This improvement secures the construction safety of subsequent shield tunneling operations. The research outcomes can serve as a reference for future similar projects.

Key words: shield tunnel, boring parameters, intelligent prediction, geological code, shield thrust, cutter head torque
