摘要：深入探讨了市政道路工程中软土地基处理技术的重要性与多样性。软土地基因其高压缩性、低抗剪强度、低透水性和易触变等特性，对道路工程的质量和稳定性构成显著挑战。针对这些特性，分析了多种软土地基处理技术，包括表层处理的几种技术，以及换填法、排水固结法、粒料桩法、静压管桩等，每种技术均旨在通过不同机制增强地基的承载力和稳定性，同时为市政道路工程建设提供理论依据和技术参考，推动软土地基处理技术的进一步发展与应用。
Abstract: This article delves into the importance and diversity of soft soil foundation treatment techniques in municipal road engineering. The high compressibility, low shear strength, low permeability, and easy thixotropy of soft soil foundation pose significant challenges to the quality and stability of road engineering. Based on these characteristics, various soft soil foundation treatment technologies have been analyzed, including several surface treatment techniques, as well as replacement filling method, drainage consolidation method,granular pile method, static pressure pipe pile method, etc. Each technology aims to enhance the bearing capacity and stability of the foundation through different mechanisms, and provide theoretical basis and technical reference for municipal road engineering construction,promoting the further development and application of soft soil foundation treatment technology.
