粗粒土路基填料动静力学特性及调控改良研究综述
Review on dynamic and static mechanical properties,regulation,and improvement of coarse-grained soil fillers for road subgrades
摘要
Abstract
Accurately understanding the engineering properties of coarse-grained soil is the key to constructing high-quality road subgrades,thereby ensuring long-term stability and controlling settlement.Under static and dynamic loads,the mechanical properties of coarse-grained soil undergo complex evolution caused by particle rearrangement and breakage,which easily induces road subgrade distresses such as excessive cumulative deformation and differential settlement.In view of the key technologies involved in the deformation and control of coarse-grained soil subgrades,relevant Chinese and international research findings were systematically reviewed in this paper,and the static mechanical properties,cumulative deformation under traffic loads,particle breakage mechanism,and regulation and improvement technologies of coarse-grained soil were mainly summarized and analyzed.Based on the analysis results,it is suggested that future research should focus on strengthening the quantitative correlation between particle breakage and mechanical property degradation,long-term performance evolution under multi-field coupling,and synergistic control of intelligent compaction and material design.This promotes the formation of a comprehensive improvement scheme from material improvement and structural design to performance regulation,providing theoretical support for ensuring the long-term service performance of road subgrade engineering.关键词
