摘要
"公路处治土路基长期性能研究"项目通过对大量的工程调研、室内外试验、理论分析、数值模拟和现场监测等综合手段,系统研究了典型处治土路基在干湿循环、冻融循环和淋滤作用等环境因素与荷载作用下的工程特性及其影响、长期强度与变形规律,建立了考虑路基路面协调作用、基于动强度理论的处治土路基设计方法框架体系与指标,提出了提高处治土路基长期性能的工程技术措施,同时结合研究成果成功修筑了实体工程,编制了《公路处治土路基设计施工技术指南》。本篇介绍了该项目的主要创新性研究成果、项目的应用及推广情况,对于完善路基设计理论和方法、促进行业技术进步和学科的发展具有重要理论意义。
Throught various construction investigation,in and outdoor test,theoratical analysis,data stimulation and onsite monitoring.The study on long term performance of road treatment subgrade project systematically studies the construction characteristics,long term strength and formation rules under dry-wet cycle.Freezing-melting circulation,leaching and other environmental factors and loading.It also builds a system and index that considered the pavement synergism and dynamic strength theory.Combined with the research result,the field testing project was build and the Road Treatment Design Technique Guide was edited.This chapter introduces major research result,project application and its promotion,which has big significance to theory and method completion,industry development and aca-demic advancement.
