Cushion Impact on Bearing Capacity Exerting Degree of Soil Between Piles for rammed Cement-soil Pile Composite Foundation

摘要

Basing on filed loading test results, the influences of cushion stiffiiess to the playing process of pile head and soil surface pressure in composite foundation was analyzed. Cushion stiffness will affect bearing capacity and failure mode of composite foundation with rammed soil-cement pile, which is applied in a relatively good ground. It point out that the cushion stiffness must be considered when loading test used to determine the bearing capacity of composite foundation with rammed soil-cement pile.
