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.

建筑垃圾在沿海城市软土地基加固中的应用

提出了建筑废料在软土地基加固中的应用。本文分析了软土地基的基本工程特性,计算了软土地基的承载力和压缩模量的基本值,并估算了单夯夯桩的竖向承载力的特征值,从而确定了土的参数和三击穿透的两个参数。根据粒料桩复合地基的分类和处理,设计了带有复合载体的夯扩桩的结构,确定了夯扩桩的顺序。然后根据粒料桩复合地基的功能,设计了加固工艺,并研究了具体的应用内容。结果表明,地基横向位移变化率基本稳定,最小位移为2.0 m,具有较好的稳定性。该研究可以在一定程度上找到合理的建筑垃圾利用方式。
