I’ll be brief since I have already mentioned this in a previous post and in the July GeoPrac newsletter. But today was the 40th Anniversary of the first time humans set foot on the moon. I’m embarrassed to say, but I mistakenly noted this historic anniversary as the 20th instead of the 40th anniversary in both of the above links. I’m surprised nobody called me on this, but I guess you ridiculed me in private. If you haven’t already, check out the wonderful article by Ed Nowatzki on the geotechnical engineering aspects of the lunar lander…fascinating reading, even for non-geotech types.
This has to be one of the most complex geotechnical engineering problems I’ve heard of for a building, if not for any kind of project. For starters, beneath the proposed 10-story office building referred to as Cannon Place lies the Cannon Street Train Station built in 1868. Also beneath the site are walls and foundations of a Roman Governor’s palace. In order to accommodate these features, the building has 21-m cantilevers at each end, with the load bearing happening over two groupings of columns at the 1/3 points. In section it looks quite like a 3-span bridge…without the abutments and stacked 10-stories tall! More after the break. (Images by New Civil Engineer) […]
