A Comparative Study on Shield Tunnels with Different Cross - Section Forms
Abstract: Compared with circular tunnels, the space utilization of rectangular tunnels is more efficient, with a bigger usable tunnel face and a smaller minimum buried depth, resulting in lower project demolition cost. In the past 30 years, with advanced technology, and the necessity of higher utilization of precious underground resource, tunnel engineers have paid more attention to rectangle mechanized...

A Study on the Mechanical Behavior of Pipe Curtain with New Interlock Joint in a Large Pipe Curtain-Box Jacking Project
Abstract: The development of underground space in urban area has been challenging in recent years, especially where there are underpass crossing roads with heavy traffic and where they are highly protected for environmental reasons. The pipe curtain-box jacking method has been applied in several such projects, because it causes minimal disturbance. However, experience gained from large section pipe...

A study on the security effect of the construction of new subway station on parallel subway station structure
Abstract: With the underground spaces development, there are increasing numbers of deep foundation pit engineering problems emerged in the process of the urban construction. Especially in some coastal economically developed city, deep foundation pit in soft soil area has become a high risky project. Many scholars have carried out some researches on the effect of foundation fit excavation on existing...

Applying distributed optic fiber sensor for tunnel monitoring
Abstract: Structural health monitoring has become an important aspect in tunnel engineering due to the increased need for maintenance for aging tunnels. Various types of sensors have been employed to monitor the behaviour of tunnels during their service phase. Distributed optic fiber sensor (DOFS) is a new type of sensing technology which has been used recently for structural monitoring. This sensor...

Comparison of Two Possible Alternatives for the Development of Subsurface of Historical Buildings: A Case Study in...
Abstract: The role of underground space in the development and urbanization of cities has been increasingly challenged in recent years, especially in urban areas where the surface-land is mostly occupied. This is due to factors such as the unexpected need to go underground in large-scales, the initial human settlements of the city and the fast development of infrastructure. Therefore engineers,...

Research on Mechanical Characteristics of Longitudinal Joint of Shield Tunnel
Abstract: Shield tunnel is a kind of fabricated structure which consists of segments and bolts. The existence of joints make the tunnel have the characteristic of flexibility. The longitudinal joints bear cyclic load of tension and compression when under seismic load, reflecting its features of opening and compressing. This paper combines the numerical analysis and experiments, investigating the feature...

Study on Effect of Excavation of Pit on Its Underlying Metro Tunnel
Abstract: With rapid development of underground rail transport in China, effect of foundation pit excavation on underlaid metro tunnel has been increasingly concerned since the 21st century. The excavation inevitably leads to the upheaval of the tunnel. If the deformation values of tunnel exceed their allowable values, the safe performance of tunnel will be affected. Many scholars carried out some...
