Research on construction technology of road subgrade and bridge engineering

In recent years, China's economic level has made rapid progress. The construction industry occupies a large proportion in the overall economy, and people pay more and more attention to the construction of various projects. The quality of construction projects is directly related to the safety of people's lives and property, which puts forward higher and higher requirements for the construction technology level. As we all know, road subgrade and bridge engineering have certain complexity, and construction takes time and construction environment is bad. In recent years, with the increase in the number of relevant projects, more and more problems have emerged. This article analyzes the construction technology of road subgrade and bridge engineering, focuses on the key technologies in construction, and makes the project construction as much as possible to meet the needs of human production and living.
