    Introduction of the geological 
	condition of Qingdao
 Bay Bridge
    
	
    Through detailed geological survey and 
	reconnaissance over the bridge location and nearby area, the geological 
	“code” in the entire Jiaozhou Bay Area was basically uncovered. The bridge 
	location is divided into four structural units: Jiaozhou – Wangtai Hollow, 
	Jimo – Cangkou Hollow, Xiaozhushan Heave and Qingdao – Laoshan Heave. The lithology at the 
	bridge location is mainly the lava and alloclastic rock of Qingshan Group in 
	cretaceous. To the south and over the Haoguanzhuang sunder, it was the 
	Jiaonan Heave, and the crystallized base is composed of mainly metamophic 
	rock belonging to Archaean and Proterozoic Jiaonan Group; to the east, the 
	crystallized base at the area in the east of Cangkou Sunder is granite in 
	Yanshan Period.
    
	
     
    
	
    The bedrock uncovered during survey 
	was the sedimentary rocks and effusive rock stratum in the cretaceous of 
	Mesozoic Erathem, as well as the intrusion rock of Laoshanchao Unit in the 
	later Yanshan Period.
