The ground treatment plan for the main lifting station of the wind turbine lifting platform under soft foundation conditions directly affects the construction safety

construction cost

and project schedule of wind power projects. This article proposes a combined ground treatment plan of rubble replacement

dense laying of steel rows

and roadbed steel plates. Through theoretical calculations and engineering practice

the safety

reliability

technical economy

and construction convenience of this combination scheme have been verified.And it is pointed out that the layered summation method for calculating foundation settlement does not consider the characteristics of wind turbine hoisting and the impact of platform back-filling process

and using the SkemptonBillon method to calculate instantaneous settlement is more in line with the actual situation.It provides reliable theoretical support and implementation experience for engineering practice

and has good economic and social benefits and guiding significance.
