The controller calculates a traction force of the loading machine during excavation work of excavating an object to be excavated with the bucket. The controller calculates a load height representing a height of the object to be excavated inside the bucket during the excavation work. The controller calculates an earth pressure coefficient of the object to be excavated based on the traction force and the load height.
