揭普高速公路沿线广泛分布软土层,软土性质很差,且复杂多变。为保证软土路段可满足高速公路的使用要求,必须对软基进行处理。通过对不同路段的工况条件进行仔细的分析,结合上部构筑物对稳定和沉降的要求,分别采用相应的方法对软基进行处理。实施结果表明,该项目的软基处理是成功的。信息化施工在软基处理工程中是一个很重要的环节,本工程在施工过程中,即根据反馈信息进行了一些重大的设计变更,从而保证了软基处理的质量。本工程还发现有腐木土层。初步结果表明,腐木土的力学性质与一般软土的性质有明显不同,有待深入研究。
Widely distributed soft soil layer along the highway of Jiepu, soft soil is poor in nature, and complex and changeable. In order to ensure that soft soil sections can meet the requirements of expressway use, the soft foundation must be treated. Through careful analysis of working conditions of different road sections, combined with the requirements of the stability and settlement of the superstructure, the corresponding methods were used to deal with the soft foundation. The implementation results show that the soft ground treatment of the project is successful. Information construction is a very important link in the soft foundation treatment project. During the construction process, some significant design changes have been made according to the feedback information to ensure the quality of the soft foundation treatment. The project also found rotten soil layer. The preliminary results show that the mechanical properties of rotten soil are obviously different from the properties of soft soil, which needs further study.
