Study Of Construct Garbage In Municipal Administration Road Construction

With the development of city construction, suburbs of the city construction iswide spread， and there are many fishpond in the suburb of tianjin, the foundationneed to be reinforced by replacing the silt with other material. in order to make theproject economic and protect the environment, take full advantage of the constructwaste as the exchange material.There is many papers report on the application of construction waste roadconstruction, the study on mechanism and theory of construction waste used in softfoundation soil treatment is also relatively lack, in order to make the constructionmore economic and the design more reasonable, this paper put forward the conceptof duricrust layer through the analysis of the construction waste soil physical andmechanical properties, and the calculation method of the bearing capacity is putforward, and the critical thickness calculation method is also suggested. The FEManalysis of the project is conducted.Through the research above, the optimal particle gradation and optimalmoisture content are put forward.building. the bearing character of the construct wasteunder different infiltrating effect is also suggested. Through this topic of research, theresult is expected to provide the reference and application for the similar project.
