摘要
高速公路作为现代经济和社会发展的重要基础设施,其是构筑交通现代化的重要标志。然而,很多已建高速公路在通车运营过程中往往会出现软基路段不均匀沉降现象,其中桥头跳车问题最为突出。为了保障行车舒适性和安全,必须重视软基沉降处理,采取切实可行的方案,积极消除桥头跳车等病害。基于此,本文结合具体案例,提出了FCB气泡混合轻质土换填方案,以期能够优化施工工艺,同时有效解决高速公路软基沉降病害等问题。
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.
