Research on Treatment Technology for Settlement of Highway Section on Soft Ground

As an important infrastructure for modern economic and social development, expressways are an important symbol for building traffic modernization. However, in the process of opening to traffic, many built expressways often have uneven settlement on soft ground sections, and the problem of bridgehead jumping is the most prominent. In order to ensure driving comfort and safety, it is necessary to pay attention to the settlement of soft foundations and adopt practical solutions to actively eliminate diseases such as bridgehead jumping. Based on this, this article combined with specific cases, proposed FCB air bubble mixed lightweight soil replacement program, in order to optimize the construction process, while effectively solving the problems of highway soft foundation settlement diseases and other issues.
