China's research about permafrost and permafrost foundation engineering began with railway construction on Daxinganling permafrost regions. 1960s, preliminary study about permafrost engineering for the construction of the Qinghai-Tibet railway project made China's research about permafrost and permafrost foundation engineering enter comprehensive and systematic development stage.
Currently, piles commonly used in foundation engineering of bridge and culvert on permafrost regions are steel piles and reinforced concrete piles.
CONCLUSIONS Test data indicate: The use of pile load test can be close to the actual work of pile in permafrost, and more accurately determine the ultimate capacity of bridge engineering pile, in addition can also learn about the interaction between the pile-soil and pile.
