The lateral resistance of three pile group configurations was investigated using three dimensional (3-d) finite element modeling the three pile groups considered in the study were a vertical pile group, a battered pile group, and a mix of vertical and battered piles in a group. “pile spacing effects on lateral pile group behavior: load tests” journal of geotechnical and geoenvironmental engineering, foundation analysis and design. Lpile is a special-purpose and internationally recognized computer program based on rational procedures for analyzing a pile under lateral loading using the p-y method.
Comparison with field and laboratory tests indicates that the behavior of pile groups predicted by the analysis is in qualitative agreement with observed behavior this paper demonstrates that it is possible to use the pile group analysis presented as a practical method for solving design problems.

Grouped and single pile behavior differs owing to the impacts of the pile-to-pile interaction ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon. Pdf | to investigate group interaction effects as a function of pile spacing, full-scale cyclic lateral load tests were performed on pile groups spaced at 33, 44 and 565 pile diameters in the . Fact that group behavior of pile was different than single pile and piles generally used in groups in field influence of pile inclination on batter pile groups .

Where n - the number of piles in the group the procedure explained above is not applicable if the pile tips rest on compressible soil such as silts or clays. Analyze the behavior of the pile group in uniform or layered soil several field and experimental tests reported in the literature are used to demonstrate the validity of the approach.
To improve our understanding of pile group behavior, a series of full-scale lateral load tests has been carried out on a 9-pile group (3 piles in 3 rows) driven in soft clay at the salt lake international airport.
