A Case Study for Large Excavation Constructed by Open Cutting with Under Mining Method in Xuzhou, China
Abstract: Compared with the simple excavation, the mechanical characteristics and ground deformations of the excavation constructed by Open Cutting with Under Mining (OCUM) Method are more challenging to predict. Peng-cheng Square Station is the transfer station of Metro Line 1 and Line 2 in Xuzhou, China, which was composed of a 23m-depth L-shaped open cutting foundation pit and 8 tunnels with...

A Simplified Method for Calculation of Allowable Longitudinal Dif ferential Settlement of Immersed Tunnel
Abstract: The construction condition of HongKong-ZhuHai-Macao Immersed Tunnel is very complicated of deep water more than 40 meters, soft soil layers more than 40 meters and 20 meters sedimentation loads. There are almost 5 types of foundation solutions along tunnel axis. How to determine the suitability of foundation solutions? Immersed tube tunnel is a type of underground structure which is sentisitive...

Analysis of the Influence of Metro Tunneling on Building Settlement
Abstract: Although the characteristics of ground settlement without buildings have been defined, but further research is still needed for the characteristics of settlement with buildings, and such research has more theoretical significance and engineering application value. Targeting at the specific strata and shallow foundation buildings, FLAC 3D is utilized to establish the three-dimensional numerical...

Harmful Gas Eruption Prediction and Its Protection Based on Solid-Fluid-Gas Coupling in Shield Tunneling
Abstract: In some cities in southern China, the shield machine will be encountered the geological environment of explosive harmful gas in the process of metro tunneling, combined with the shield machine does not have explosion-proof function, that is likely to cause harmful gases gush out in a moment and induce harmful gas exceed standard even explode. Therefore, solid-fluid-gas coupling theoretical...

The Analysis of the Lining Cracks Caused by the Cavity behind Lining in the High-speed Railway Tunnel Based on XFEM
Abstract: For the past ten years, a large number of tunnels have been built with a large-scale construction of high-speed railway in China. Some severe repair and maintenance problems follow it at the same time, in which the lining crack and cavity behind lining are two major potential threats to the traffic safety of high-speed trains. It is very common for the separate research about the reducing of...
