摘要
根据TBM开挖碴料、掘进参数,通过在TBM刀头和护盾窗口对岩体的观察,结合已掌握的地质资料、水量大小,综合确定围岩类型,预测前方岩体情况。这对开挖费用确定,支护管片类型选择和指导TBM快速安全掘进意义重大,因此总结分析TBM围岩类型确定和预测方法很有必要。
It will play an important part in determining excavating expense, supporting segment types choices and instructing TBM safe and foreseeing in front rock conditions within IBM to analyze surrounding rock of double-shield TBM excavating tunnel according to excavating muck, boring parameter, observation of TBM, shield windows and ground water quantity.
