高速公路施工中的软土路基施工技术

Construction Technology of Soft Soil Roadbed in Expressway Construction

公路建设的质量对道路使用的安全性和稳定性至关重要。基于此,首先深入研究了软土路基的特征,包括其高含水量、流变性、稳定性、压缩性以及相对较弱的荷载性能。这些特征为软土路基施工带来了独特的挑战。同时,详细分析了软土路基施工中存在的问题,如路堤滑坡、开裂和沉降等。这些问题可能会对公路的安全性和持久性造成严重影响。为了应对这些挑战,提出了软土路基施工技术的处理优化策略。这些策略包括土壤改良和加固、排水系统的改进、真空管网和密封系统的应用,以及其他施工技术的优化,如强夯、挤密、抛石挤淤和土钉墙等。这些措施旨在确保公路施工达到既定标准,并提高道路使用后的安全性和稳定性。

The quality of highway construction is crucial for the safety and stability of road use.Based on this,a thorough study was conducted on the characteristics of soft soil roadbed,including its high moisture content,rheological properties,stability,compressibility,and relatively weak load performance.These characteristics bring unique challenges to the construction of soft soil roadbed.At the same time,a detailed analysis was conducted on the problems existing in the construction of soft soil roadbed,such as embankment landslides,cracking,and settlement.These issues may have a serious impact on the safety and durability of highways.In order to address these challenges,optimization strategies for the treatment of soft soil roadbed construction technology have been proposed.These strategies include soil improvement and reinforcement,improvement of drainage systems,application of vacuum pipe networks and sealing systems,and optimization of other construction technologies,such as dynamic compaction,compaction,riprap and soil nailing walls.These measures aim to ensure that road construction meets established standards and improve the safety and stability of the road after use.
