随着现代交通车流量的不断加大,为了节约资源,优化土地利用,高速公路拓宽施工案例越来越多,其中多数路段需进行填方路基拓宽作业,由于新旧路基填料、压实度等差异性,传统工艺施工无法满足拓宽质量需求,必须要根据实际情况,综合分析各因素,选择确定最为合适的施工技术,保证路基结构强度达标,以免拼接路段出现不均匀沉降问题。本文对高速公路路基拼宽施工技术要点进行简单分析。
With the increasing traffic of modern traffic vehicles, in order to save resources and optimize land use, there are more and more cases of highway widening construction, of which most of the sections need to be filled with roadbed. Because of differences in packing and compaction of old and new subgrade, It is necessary to comprehensively analyze various factors and select the most suitable construction technology to ensure the structural strength of subgrade to meet the standard so as to avoid the uneven settlement of the spliced sections according to the actual situation. This article briefly analyzes the key points of highway subgrade construction technology.
