摘要
本文根据23个静载试验与超重型动力触探的对比资料，并结合以卵石层作天然地基已建成的高层建筑变形观测资料与理论公式计算变形量的对比，提出用N120锤击数评估宜昌地区卵石层地基承载力和变形模量的方法，对宜昌地区卵石层地基的勘察与评价提供了可供参考的实践经验．
According to the comparison between results of 23 static loading tests and extra heavy penetrometer tests and also the comparison between observed deformation of high-rise buildings on cobble subgrade and the de formation calculated by theory. Blow count (N120) is used to evaluate the bearing capacity and the modulus of de formation of cobble subgrade. It is cosidered to be an practical experience which may be consulted for investigation and evaluation the usability of cobble subgrade in Yichong, Hubei.
