摘　　要：由于山区公路改扩建工程的施工环境较为复杂,导致施工进度受到影响并且交通与工程之间互相干扰。本文基于路基路面拼宽处理技术改扩建公路路面有限元分析,考虑路面拉应力分布情况,提出基于路基路面拼宽处理技术的山区公路改扩建工程施工方法。选择新建路面面层材料,加宽两侧路基,完成公路改扩建的施工过程。实验结果表明,使用改进施工方法时各个测量点的路面变形偏差均低于施工最大允许偏差,表明该方法的施工效果较为良好。Due to the complex construction environment of mountain highway reconstruction and expansion project,the construction progress is affected,the traffic and the project interfere with each other.Based on the finite element analysis of highway pavement reconstruction and expansion based on subgrade pavement widening processing technology,considering the distribution of pavement tensile stress,this paper proposes a construction method for mountain highway reconstruction and expansion project based on subgrade pavement widening processing technology.New pavement surface material is selected and the subgrade on both sides is widened to complete the construction process of highway reconstruction and expansion.The experimental results show that,when the improved construction method is used,the pavement deformation deviation at each measurement point is lower than the maximum allowable deviation of construction,indicating that the construction effect of this method is relatively good.
