摘要
拟建的渤海海峡隧道采用隧道掘进机(TBM)施工极具挑战性,其中关键之一就是TBM的掘进速率预测问题。本文将渤海海峡隧道和澳大利亚Clem Jones隧道进行工程类比,并介绍了比能法在Clem Jones隧道的应用情况。在Clem Jones隧道施工过程中,相关研究人员运用比能法对TBM的可掘性进行了分析及预测,从后期的掘进情况来看比能法的预测结果与实际施工吻合得较好。本文在Clem Jones隧道和渤海海峡隧道对比分析的基础上,认为运用比能法预测TBM的可掘性同样适用于渤海海峡隧道的TBM施工。
The proposed Bohai Strait tunnel is a challenging project,and penetration rate of tunnel boring machine（TBM）is one of the keys. This paper made a contrast between the Clem Jones tunnel in Australia and the Bohai Strait tunnel,and introduced the specific energy used in the Clem Jones tunnel. During the construc-tion of the Clem Jones tunnel,researchers made the analysis and forecasted about the TBM’s penetration rate us-ing the specific energy,which was identical to the practical construction very well. This paper concluded that the specific energy can be used in the Bohai Strait tunnel as well as the Clem Jones tunnel,which was based on the comparative analysis of the Clem Jones tunnel and Bohai Strait tunnel.
