The photo of this failed SPL wall is pretty remarkable. It was discussed in a thread I came accross on EngTips.com. The originator of the thread (kleo) says he was involved from the contractor side on this project in a mountainous rainforest region near Cuba. He also says the wall was designed by “FHWA”, don’t know if that means US FHWA or what. But if so, I have no idea where this project would be located. The wall was designed for a 15-ft high cantilever with around 20-ft embedded with the last 7-ft being into bedrock. Check out the thread to kick in your hypothesis for kleo.
A 13-story apartment tower in the Lotus Riverside Development toppled over almost intact in Shanghai on June 26. The apartment building was still under construction and one worker was killed. According to the Shanghai Daily, there was an excavation for an underground parking garage immediately next to the failed structure. From the photos and video, it appeared that the building fell away from the excavation. More info and video after the break. (Imaginechina via AP Images via Wall Street Journal)
