On the calculation method of bearing capacity of combined-pile composite foundation

摘要

Based on study on the existing calculation method of bearing capacity of combined-pile composite foundation,consider the behavior of loaded combined-pile composite foundation and the general influence of construction method to the bearing capacity of soil, two coefficients, soil bearing capacity exertion coefficient and soil bearing capacity improvement coefficient, are introduced,a new step-by-step calculation method of bearing capacity of combined -pile composite foundation is put forward. It shows that computed data is in agreement with experimental date of loading test by example project.
