Abstract
In this paper, the application of construction waste in soft soil foundation reinforcement is proposed. This paper analyzes the basic engineering characteristics of soft soil foundation, calculates the basic values of bearing capacity and compression modulus of soft soil foundation, and estimates the characteristic value of vertical bearing capacity of single rammed expanded pile, so as to determine the soil parameters and the two parameters of three blow penetration. According to the classification and treatment of the composite foundation of granular material pile, the structure of rammed expanded pile with composite carrier is designed, and the order of rammed expanded pile is determined. Then according to the function of the composite foundation of granular material pile, the reinforcement technology is designed, and the specific application content is studied. The results show that the change rate of the lateral displacement of the foundation is basically stable, and the minimum displacement is 2.0 m, which shows good stability. This study can find a reasonable utilization way for construction waste to a certain extent.
