Abstract

The invention provides a soft soil roadbed structure system and a construction method. The soft soil roadbed structure system comprises a subbase layer structure, a base layer structure, a surface layer structure and a guide and drainage structure. The subbase layer structure comprises a geopolymer anti-sliding baffle, a geopolymer reinforced soft soil layer, a geopolymer constraint pipe pile and a soft soil foundation. The base layer structure comprises a geopolymer bearing frame, a cushion layer, a geopolymer concrete liner layer, a modified clay tamping layer and a geopolymer green plant planting groove; the surface layer structure comprises a geopolymer stabilized macadam layer and an asphalt geopolymer concrete layer; the guide and drainage structure comprises a geopolymer drainage groove and a drainage ditch. According to the soft soil roadbed structure system, the green inorganic cementing material-geopolymer which is high in compressive strength, good in early strength anti-permeability performance, high in acid and alkali resistance, low in carbon and environmentally friendly is adopted for preparing the soft soil roadbed structure system, uniform settlement of a roadbed can be achieved, and the roadbed slope stability is improved; the structure has the advantages of simple and reliable structure, good durability, high ecological restoration rate, high construction efficiency and low later maintenance cost.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a soft soil subgrade structure system and a construction method. Background technique [0002] Highway engineering is a key project of my country's transportation. With the vigorous development of my country's economic construction, the number of roads built under special geological conditions is increasing year by year, and soft soil is especially common in engineering construction. Soft soil has the characteristics of high natural moisture content, large void ratio, high compressibility, poor mechanical properties and high sensitivity. At present, the soft soil foundation is generally reinforced with cement deep mixing piles. First of all, the engineering environment faced by cement deep mixing piles in the construction process becomes more complex and harsh, and under the action of various ions in the soil, the compressive strength and durability of cement so...
