Tangshan City, the old single-storey houses for the old-fashioned, turned into rubble after the earthquake; the new urban area are multi-storey brick-concrete structure buildings, wiped out almost collapsed; reinforced concrete frame structure is also not spared the high-rise buildings, railway track occurred in snake shape distortions or subsidence as a result of the roadbedcheng bo lang style ups and downs, have a large surface cracks, the general collapse of a bridge destroyed, seismotectonic cracks extended up to 8 kilometers, with cracks near the ground motion is very alarming, two of its more than 200 meters within the scope of even the people air have been thrown.

唐山市老区多为老式单层民房，震后变成一片瓦砾；新市区大多是砖混结构多层建筑，几乎倒塌殆尽；钢筋混凝土框架结构的高层建筑物亦未能幸免，铁路轨道发生蛇形扭曲或由于路基下沉而呈波浪式起伏，地表产生宽大裂缝，桥梁普遍塌毁，地震构造裂缝延伸达 8公里，裂缝带附近的地面运动非常惊人，其两则200多米的范围内连人都被抛向空中。

Combining with project practice, this paper introduces checking method of grit road foundation solidness in super road project.
