Comparison Analysis of GFRP Anchor Pile Performance in Expansive Soil Foundation

Abstract:

GFRP anchor pile is to be researched and promoted in expansive soil foundation of tower buildings and underground buildings. Expansive soil area was selected, and comparison scheme of reinforced concrete anchor pile and GFRP anchor pile was designed. Uplift and compressive ultimate bearing capacity comparison experiment was done by one grouting, twice grouting, water cement ratio and soak. The performance of the two types of anchor pile each has advantages and disadvantages. Durability, safety, economy are considered, and traditional method of anchor pile can be improved. GFRP anchor pile and reinforced concrete anchor pile can be used in combination, and that can be better used in expansive soil foundation.
