Research on Pile Foundation Construction Technology of Steep Slope Bridge in Mountain Area
In order to improve the construction quality of steep slope bridge pile foundation in mountainous areas,this paper takes a mountain bridge project as an example,analyzes the construction technology of steep slope bridge pile foundation in mountainous areas in detail,and e-valuates the construction effect and social and economic benefits.The results show that the axial compressive strength of pile concrete is 36.8kPa,the wave velocity of pile is3 500～4 650 m/s,and the integrity of pile body is good.The bearing capacity of pile body reaches18,000 kN,and the maximum settlement of pile body is 21.3mm,both of which do not exceed the warning value in the design requirements,and meet the requirements in JTG 3363-2019 Code for Design of Foundation and Foundation of Highway Bridges and Culverts.The construction effect is good and has significant social,economic and environmental benefits.
