Abstract
In order to analyze the settlement characteristic of composite foundation for cement mixing piles in soft soil, the settlement characteristics of composite foundation for single and four cement mixing piles in soft soil were analyzed by loading. The test results show that the settlement of composite foundation for single and four cement mixing piles, under different loads, includes two stages, i.e., quick settlement and slow settlement. At the stage of the quick settlement, composite foundation settles fast. 90% of the total settlement for the loading takes place during the quick settlement, and the remaining 10% of the settlement occurs during the slow settlement. In different load stages but in the same period, the relation of settlement ratio and time of composite foundation for single and four cement mixing piles is similar. The relationship between settlement and time can be described by Hill model.
