Strength Response Parameters of Natural Soil Surfaces and Their Application to the Landing Problem of Aircraft

摘要

A suitable rheological model is found to represent the soil deformations under impact loads. The parameters of the model are evaluated from the deceleration history curves of the Princeton impact penetrometer tests. From the soil parameters obtained, the soil responses under the airplane landing load are estimated. Extensive applications to the dynamical soil problems, such as soft landing of spacecraft, will be possible. (Author)
