Future Evening Meetings

Due to the ongoing situation with Covid-19 and Government's policies, the Institution of Civil Engineers is closed for all events until the 1st May – we therefore will not have a BTS meeting in April. The April BTSYM meeting will be streamed live. The BTS holds monthly evening meetings from September to June, generally on the third Thursday of the month. Unless otherwise stated, the meetings are at the Institution of Civil Engineers (ICE) with the lecture starting at 6pm. Additional meetings are arranged by the BTS Young Members, by regional groups and as joint meetings with other societies.

Joint BTSYM/TACYM July Meeting: Time-Dependent Deformations of Shafts and Tunnels in the Greater Toronto Area

The shales of the Greater Toronto Area (GTA) experience time-dependent defor-mations (TDD) which are known to be the result of volume change of rock. This change is due to diffusion and dissolution of calcite that is inherent to the shale for-mation upon introduction to fresh water during excavation and stress relief. These deformations can induce long-term pressures on shaft walls and tunnel linings, especially if the permanent works are constructed soon after excavation with little time delay. This talk will present measurements of TDD of recent shaft and tunnel projects constructed in the GTA, and draw conclusions regrading the design impacts for engineers and owners.
