Method for adjusting anti-thrust rigidity of pile group foundation
The invention relates to the field of pile foundation projects, in particular to a method for adjusting the anti-thrust rigidity of a pile group foundation with a large pile length difference. Bedrock is broken within the radial range of 0.3 m-0.5 m in a semicircular region behind short piles in the thrust direction, a behind-pile constraint release region is formed, the behind-pile constraint release region is filled with graded granules with certain granule strength, and the graded granules are tamped. The length of the behind-pile constraint release region is determined through a numerical analysis method. The anti-thrust rigidity of the pile group foundation with the large pile length difference can be adjusted, and the problem that when the pile group foundation with the large pile length difference bears horizontal thrust in a place with large bedrock surface fluctuation, the horizontal thrust is not evenly distributed due to the uneven rigidity of the pile foundation is solved.
