Research on Construction Technology of Subgrade and Pavement in Settlement Section of Municipal Road and Bridge Engineering
This paper discusses the influence of differential settlement on pavement structure and its control standard.Firstly,it analyzes the cause of differential settlement and its influence on pavement cracks,depres-sions and other diseases.Based on the theoretical hypothesis,the differential settlement model of the old road and the new road was established,and the quadratic parabola function and parabola feature were used to describe the settlement distribution respectively.Then,the control standard of uneven settlement of roadbed was put forward,and the influence of material selection,structural design and other key factors on pavement widening was empha-sized.Finally,through the analysis of the detection results of the subgrade in different time nodes of the settle-ment section,it is found that the settlement amount increases gradually with the passage of time,but tends to be stable in the later period.The research shows that the construction technology and monitoring measures for the settlement section roadbed are very important to ensure the long-term stability and safety of the roadbed,which provides a valuable reference for the future municipal road and bridge projects.
