摘要:Abstract(#br)The muck in the excavation chamber and the screw conveyor of Earth Pressure Balance (EPB) TBM, which comprises soil and rock fragments, is often conditioned to adjust its properties for more efficient operation of the machine. The target properties of the conditioned...

摘要:Abstract(#br)Tunnels often suffered severe seismic damage when passing through the active fault in high intensity earthquake area. The fault movement might be divided into fault movement and seismic motion under the strong earthquake action, and both of them could have the signif...

摘要:Abstract(#br)Underground structures often pass beneath high-rise buildings or are located close to them in megacities. Given complex site-city interactions, conventional earthquake engineering practices may leave megacities in seismically prone areas in potential danger. Rat...

摘要:Abstract(#br)During the cavern excavation, the underground seepage boundaries are constantly changing, and the seepage field is in an unstable state. Meanwhile, most underground caverns are not constructed with grouting curtains and drainage holes during excavation. The cave...

摘要:Abstract(#br)For a shield tunnel structure in fire, the thermal-mechanical behavior of tunnel lining segments plays a key role in determining the failure process. Due to the restriction at the segment ends, secondary stress will be induced, and this is particularly the case when ...

摘要:Abstract(#br)The utility tunnel provides enough spaces, dry environment, better monitoring and maintenance for municipal pipelines. When gas pipelines are incorporated into the utility tunnel, the flammability and explosion property of the natural gas would threaten its safe oper...
