| Nowadays,with the rapid development of urban construction,the problem of how to deal with a huge amount of construction waste rationally and effectively has been raised in many countries.In this paper,the application of building waste recycling materials in foundation treatment was studied,the purpose was to solve the problems of transportation,stacking and treatment of construction waste effectively.At the same time,it provides experimental data and empirical theory for solving the problem of collapsible loess treatment.It offers a theoretical basis for the effective application of construction waste recycled materials in the special foundation treatment of highway,and also save resources and reduce project investment,also create significant social benefits,economy benefits and environmental benefits.Firstly,through a series of indoor experiments,we explored the physical and mechanical properties of recycled materials from construction waste preliminarily.The mechanical properties of the mixture of construction waste and other materials were discussed.The combinations were obtained by changing the fine material and fine material ratio in the mixture.through experiments.Through the experiments,the optimal mix ratio was obtained by using the construction waste recycled materials as the coarse aggregate of pile packing.Secondly,multiple combinations were obtained by changing the parameters like pile packing and pile spacing.Through a series of outdoor tests,it has verified the effect of the compaction piles of building waste recycled materials under different combinations,the mechanical change rules of various combinations were analyzed and compared.At last,the parameters such as the type of pile packing and the number of ramming in each layer were added,and a reasonable test combination was designed by orthogonal analysis.Through the corresponding outdoor test data,the order of the effect of each factor was analyzed and the optimal combination of parameters was obtained. |
