摘　　要：高速公路路基工程建设中,不良土质的存在会导致路基变形、塌陷等质量问题,威胁工程安全。有效改良不良土质路基,对于确保高速公路工程质量、延长使用寿命意义重大。以高速公路路基不良土质的种类及成因为切入点,系统分析了膨胀土、湿陷性黄土、高液限土、冻土等不良土质的形成原因。针对不同类型不良土质特点,详细介绍了多种改良技术与施工方法,旨在为高速公路不良土质路基改良施工提供技术指导。In the construction of highway subgrade engineering,the presence of poor soil quality can lead to quality problems such as subgrade deformation and collapse,posing a threat to engineering safety.Effectively improving poor soil subgrade is of great significance for ensuring the quality of highway engineering and extending its service life.This article takes the types and causes of poor soil quality in highway embankments as the starting point,and systematically analyzes the causes of poor soil quality such as expansive soil,collapsible loess,high liquid limit soil,and frozen soil.Based on the characteristics of different types of poor soil,various improvement techniques and construction methods were introduced in detail,aiming to provide technical guidance for the improvement construction of poor soil subgrade on highways.
