Study on key points of soft soil subgrade construction technology in road and bridge engineering construction

China has a very vast territory of state, so the geological environment between different regions is quite different, which increases the difficulty coefficient in the construction process. It is impossible to use unified standards for road and bridge construction. It is very common to encounter various complex problems in the process of construction team construction, among which the construction on soft soil subgrade is a common problem in current road and bridge engineering. Through analysis, this paper analyzes and elaborates the construction technology of soft soil subgrade based on the construction of road and bridge engineering in detail to help the construction personnel and provide them with certain reference.
