wiki了一下这个mk84,这么个大杀器。。。
The Mark 84 has a nominal weight of 2,000 lb (907 kg), but its actual weight varies depending on its fin, fuze options, and retardation configuration, from 1,972 to 2,083 lb (894 to 945 kg). It is a streamlined steel casing filled with 945 lb (429 kg) of Tritonal high explosive.[8]
The Mark 84 is capable of forming a crater 50 feet (15 m) wide and 36 ft (11 m) deep. It can penetrate up to 15 inches (38 cm) of metal or 11 ft (3.4 m) of concrete, depending on the height from which it is dropped, and causes lethal fragmentation to a radius of 400 yards (370 m).
那个停车场大概50米x20米这样,弹坑在中间,所以距离建筑物大概10-25米。
假设里面tnt有400kg,学civil engineering的大牛应该可以算附近建筑物受到的冲击波。
粗略计算,暂时找到un网站上有一个kingary-bulmash blast计算器
https://unsaferguard.org/un-saferguard/kingery-bulmash
incident pressure 143kPa, 相当于20.74psi
按照cdc文献冲击波的破坏,
https://www.cdc.gov/niosh/docket/archive/pdfs/niosh-125/125-explosionsandrefugechambers.pdf
20psi是最下面一档,heavily built concrete building are severely damaged or demolished。。。从目前现场照片看,屋顶掉了瓦,窗户破了,大概只有1-2psi的样子,哪里有点不对啊
