摘要
随着我国公路建设的快速发展,软土地基处理成为制约工程质量和运营安全的关键问题。本文系统分析了软土地基高含水量、高压缩性、大孔隙比及低抗剪强度等特性对公路工程的危害,并基于物理、化学及改良处理技术的特点,提出综合处理方案的设计原则与实施流程。通过引入实际工程案例,结合真空预压、水泥搅拌桩复合地基及土工合成材料等技术的协同应用,验证了综合处理方案在控制沉降、提升承载力和缩短工期等方面的显著效果。本研究进一步探讨了新材料、智能化设备及绿色工艺的创新方向,强调因地制宜与技术、经济相结合的重要性,为复杂地质条件下公路工程软土地基处理提供了理论支持与实践参考。
With the rapid development of highway construction in China,the treatment of soft soil foundation has become a key issue that restricts engineering quality and operational safety.This article systematically ana-lyzes the hazards of high moisture content,high compressibility,large porosity,and low shear strength of soft soil foundation to highway engineering.Based on the characteristics of physics,chemistry,and improvement treatment technology,the design principles and implementation process of comprehensive treatment plan are pro-posed.By introducing practical engineering cases and combining the collaborative application of technologies such as vacuum preloading,cement mixing pile composite foundation,and geosynthetic materials,the signifi-cant effects of the comprehensive treatment scheme in controlling settlement,improving bearing capacity,and shortening construction period have been verified.The study further explored innovative directions for new mate-rials,intelligent equipment,and green processes,emphasizing the importance of combining local conditions with technological and economic considerations,providing theoretical support and practical reference for soft foundation treatment in highway engineering under complex geological conditions.
