The settlement-adjustable wind turbine foundation is a new form of active settlement-regulated wind turbine foundation suitable for deep dump ground layer. The model test method was used to investigate the differences in the force response and deformation patterns of the various components of the traditional gravity wind turbine foundation and the settlement-adjustable wind turbine foundation during operation under horizontal cyclic loading. The test results show that: under horizontal monotonic loading conditions
the ultimate bearing capacity of the settlement-adjustable foundation is better than that of the traditional gravity foundation
with an increase of about 160%; under horizontal equal-amplitude short-term cyclic loading conditions
the amount of change in the inclination of the foundation of the same foundation form and the size of the amplitude of the cycle load are positively correlated
and the amount of change in the inclination of the settlement-adjustable foundation of the same amplitude of the load is obviously smaller than that of the gravity foundation; under horizontal variable-amplitude long-term cyclic loading conditions
the amount of change in the inclination of the settlement-adjustable foundation is significantly smaller than that of the gravity foundation. Under the condition of horizontal amplitude long-term cyclic loading
the amount of change of inclination
displacement and soil pressure of settlement-adjustable wind turbine foundation keeps obviously smaller than that of gravity-type foundation. The axial force of settlement-adjustable wind turbine foundation keeps increasing during the loading process
but the growth rate is gradually slowing down
and the increment of axial force decreases with the increase of monitoring depth of the pile body.
