摘要

隧道盾构掘进机(TBM)掘进时难以及时地、有效地评估掌子面岩石强度，导致现场施工过程中很难客观地判别岩爆、卡机等施工风险。在前人研究成果和工程实践的基础上，提出一种基于TBM掘进参数的现场岩石强度快速估算方法，对掌子面岩石强度进行实时评价。通过TBM规格、掘进参数与岩石强度的力学分析，建立了现场岩石强度快速估算公式。基于对国内外多条隧道TBM数据的统计拟合分析，确定了估算公式中系数常量与TBM参数（开挖直径、刀具尺寸）的相关性，以多个典型TBM工程实例进一步验证了所提经验公式的普适性与可靠性。研究结果可为TBM工程岩石强度的快速现场估算提供新的切实可行的思路。

Abstract

It is difficult to estimate the detailed rock strength of excavating face timely and effectively when tunnel boring machine(TBM) advances

which results in it difficult to predict the risk of rockburst and TBM jamming. Based on previous research results and engineering practices

a method for estimating rock strength using TBM parameters is proposed for real-time in-situ estimation of rock strength. The equation of real-time estimation is established by the mechanical analysis between TBM specifications

excavation parameters and the rock strength. Then the relationships between the constants in the equations and the TBM specifications such as excavation(tunnel) diameter

cutter diameter are determined in this study on the basis of data collected at several tunnels. Typical TBM case studies for application further verified the wide suitability and reliability of the novel equations. The proposed method appears to be promising and feasible for real-time in-situ estimation of rock strength.
