Abstract: [Abstract] In order to study the working principle of cement sand cushion, the optimum mix proportion of cement sand cushion is further understood in the physical properties of cement sand cushion and the design requirements. Based on the engineering example, this paper introduces the design features of cement sand cushion in large area. This paper introduces the experimental results, economic effects and performance analysis of composite foundation of cement sand cushion;
