炭质泥岩工程力学特性及公路路堤施工技术研究
摘要
Abstract
This paper uses the experimental method and comprehensive case analysis method to use the carbon mudstone embankment of a construction section of the Libo-Hechi Expressway construction project as the test section.By discussing the mechanical characteristics of the carbon mudstone project,the construction technology of the carbon mudstone embankment of the highway is analyzed,and the construction acceptance results of the carbon mudstone embankment of the highway are summarized.The results show that the mechanical performance parameters such as bearing ratio,plasticity index,liquid limit,disintegration resistance index,and uniaxial compressive strength of the carbonaceous mudstone samples meet the requirements for embankment filling.During the construction process of highway carbonaceous mudstone embankment,technologies such as bottom ballast replacement and filling,edging treatment,layered paving and filling,and multiple rolling are comprehensively applied.Finally,the compaction,porosity,and settlement difference of the carbonaceous mudstone embankment are all up to standard.关键词
