Research Highlights

TBM Tunnelling in difficult ground

TBM Tunnelling in Soft Ground

In recent years, several large size shield tunnels have been constructed in urban areas at shallow depth with the increasing practical demands, such as accessibility, serviceability and economy. The Groene Hart Tunnel, completed in 2005 in the Netherlands, was constructed using a slurry shield machine with an outside diameter of 14.87 m. The M-30 Tunnel in Madrid excavated by Earth Pressure Balance (EPB) shield machine, 15.2 m in diameter, was until recently the biggest shield tunnel completed in the world. In September 2006, two massive 15.43 m diameter slurry shield machines began work on the Shanghai Yangtze River Tunnel. Thus, in recent years, more and more attention has been paid to the face stability of large shield-driven tunnels. For given ground conditions, what is the maximum dimension that we could build with our present shield construction technology? Is the failure mechanism of extra large shield tunnels still the same as smaller or normal size ones? When does size count? These questions need to be answered by today’s engineer.

TBM Tunnelling in Jointed and Faulted Rock Mass

With the application of TBM in the construction of tunnels, increasing simulations are taken on TBM tunnels. We proposes the concept of utilizing block theory to simulate TBM tunnels in discontinuous rock masses and predicate the stability of surrounding rock blocks in TBM tunnels for the first time in the world. Besides, the basic theory of the simulation on TBM tunnels with the block theory has been established through three parts: simplification of thrust and torque from the cutterhead, block classification of TBM tunnels and simulation on the excavation progress. Also, a simplified model of TBM tunneling has been established based on the software BLKLAB (coded by our research group) so as to simulate the progress of TBM advancing and to predicate the stability of surrounding rock blocks.

 

Objective

To reveal and visualize the performance TBM tunneling in difficult ground; and 2) to advance TBM performance predicting model and smart TBM tunnelling system.

 

Approach

Key block theory, model tests and field tests were simultaneously adopted herein to study the performance of TBM tunnelling.

 

Significant Results and Potential Impact

The TBM tunneling performance in difficult ground could be efficiently analyzed and visualized based upon a novel model, and a smart and robust TBM tunnelling system, which was based upon BLKLAB and TBMStudio developed by our Smart-TBM Group.
