Dynamic Studies on the Bearing Capacity of Piles. Phase III. Volume I.

摘要

An automated prediction scheme is presented which uses both measured force and acceleration at the top of the pile as input and computes the soil resistance forces acting on the pile during driving. The distribution of these resistance forces acting along the pile is also determined. Shear and dynamic resistance forces are distinguished such that a prediction of total static bearing capacity is possible. Using the shear force prediction, a static load versus penetration curve is computed for comparison with the result from a corresponding field static load test. Using stress wave theory two simplified methods are developed for predicting static bearing capacity from acceleration and force measurements. These methods can be used during field operations for construction control when incorporated in a special purpose computer. (Author)
