A study of interaction effects due to bored tunnels in clay
… to understand the effects that this will have on adjacent structures, for example, the state of Singapore, which has been expanding its underground transit system extensively. The effects of tunneling twin tunnels in Singapore marine clay are outlined, analyzed and discussed. Three different …

Buckling and friction-based linear motion clutch with application to medical devices
… attempts at correct placement causing injury to adjacent structures or infusions into inappropriate spaces. Existing catheter insertion methods do not uniformly provide needle tip location feedback, nor prevent the needle from going beyond the target space. This research achieved the development …

Three-Dimensional Analysis of Geosynthetic Reinforcement Used in Column-Supported Embankments
… for faster construction and/or where there are adjacent structures that would be affected by settlement caused by the new embankment. The geosynthetic reinforcement is placed in the bridging layer to help transfer the load to the columns and decrease the total and differential settlements. …
-
Three-Dimensional Finite Difference Analysis of Geosynthetic Reinforcement Used in Column-Supported Embankments
… differential settlements of the embankment or adjacent structures are a concern and to minimize construction time. Recent increase in the popularity of this composite system has generated the need to further investigate its behavior and soil-structure interaction. Current models of …
