Long-term settlement behavior of ground around shield tunnel due to leakage of water in soft deposit

Huaina WU, Yeshuang XU, Shui-long SHEN, Jin-chun CHAI

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2,   Pages 194-198 doi: 10.1007/s11709-011-0105-y

Abstract: The lining of shield tunnel is usually composed of segments, in which the joints, cracks, and the groutingDuring the long-term running, soils and groundwater may leak from these kinds of lining deficit.The leaking of soil and groundwater causes the long-term ground loss around tunnel and thus results inThis paper aims to analyze the impact of the leakage of groundwater through segments on the long-termshow that settlement of ground surface increases gradually with the increase of the leaked volume of tunnel

Methodological Approach on Virtual Simulation for Water Diversion from South to North in Western China

Li Boheng

Strategic Study of CAE 2003, Volume 5, Issue 5,   Pages 19-23

Abstract:

The south-north water project have been listed in the Tenth Five-Year Plan. Recently the east line and middle line in this project have been ready to start working. In order to change the status of lacking water in north of China, this paper discusses the necessity and the feasibility of diverting water from the southwest trunk rivers with the digital earth virtual technique, including the amount of water diverted, the geologic bedrock, the optimum line of diverting water and the impact on entironment.
