The analysis and computation of the bearing capacity of rigid piles under inclined loads is usually based on a simplified pressure distribution along the pile length. Test data of actual pressures on such piles are scarce. Experiments were conducted with an instrumented 75 mm rigid circular pile embedded in homogeneous sand. The ultimate capacity of the pile was experimentally determined for different loading conditions and compared with analyses and test data reported previously. The interaction relationship of the load inclination on the ultimate capacity was obtained in the form of a polar diagram. Keywords: piles, lateral loads, cohesionless soils.

This paper explores the methods used widely in China and western world interpreting the ultimate capacity of driven piles based on axial static load tests. A database consisting of 57 prestressed high- compression-capacity concrete pipe piles, which are widely used in soft soil ground conditions for building and transportation projects in China, is built. Two methods widely used in China and western world to interpret the ultimate capacity of driven piles based on axial static load testing data, S-lg(t) curve and Davisson Offset Limit, are applied to the database. Findings indicate that both methods work well and reach almost the same estimation. Conclusions suggest that both academia and industry of China and western world should take the advantages of the methods and apply them to engineering practice.
