Research on Water Damage Phenomena and Prevention Measures in Highway Construction in Collapsible Loess Regions

Fan Haoqi

Abstract：Water damage in highway construction and maintenance in collapsible loess regions represents a significant type of distress， characterized by extensive distribution and severe damages. Accurately analyzing the causes of water damage and implementing effective prevention measures tailored to practical conditions are key focuses in highway maintenance work. This paper begins by examining the characteristics of water damage phenomena， analyzes the mechanisms behind their occurrence， and proposes targeted prevention measures. The study aims to provide references for highway maintenance practices.

湿陷性黄土地区公路水病害是指在公路运行过程中，受水分侵入影响导致黄土结构受到破坏，进而引发的路基路面及附属设施发生沉降、变形、开裂、塌陷等系列性问题，其核心机理是黄土遇水后颗粒间产生水膜润滑作用，削弱公路结构强度，甚至由于孔隙塌陷导致整体结构失稳。（剩余4540字）
