Analysis on the Action Mechanism and Quality Control of Each Structural Layer in Soft Soil Subgrade
The settlement of municipal road pavement in soft soil areas occurs from time to time.Once it occurs,it will affect the normal use of the road,cause economic losses,damage the government's image,and even threaten the public's life safety.The treatment of soft soil subgrade is directly related to the overall performance of municipal roads and is an important part of municipal road construction in soft soil areas.This paper first discusses the significance of soft soil subgrade treatment,and introduces the treatment methods of soft soil subgrade in Tianjin Binhai New Area China-Singapore Tianjin Eco-city municipal road engineering;then,the action mechanism of subgrade structural layers such as bamboo bar,mountain skin soil layer,geogrid,graded crushed stone layer and cement lime soil layer in subgrade engineering in soft soil areas is analyzed;finally,the quality control points of key links such as raw materials for each structural layer,construction process,management system,construction method,construction procedure,construction measurement,subgrade drainage are discussed.
