低路堤设计是今后我国高速公路建设发展的趋势,但是随着路堤填土高度的降低,交通荷载对路基的影响也越来越明显。文章结合连盐高速低路堤设计,从现场试验和室内试验两方面,分析研究了交通荷载作用下低路堤的动态特性,其研究结果可为在软土地基上修筑低路堤高速公路设计、施工、管理和养护提供有益的参考依据。
The design of low embankment is the trend of highway construction in our country in the future. However, as the embankment filling height decreases, the impact of traffic load on the roadbed becomes more and more obvious. Combining with the design of low salt high embankment for continuous salt mining, the dynamic characteristics of low embankment under traffic load are analyzed from two aspects of field test and laboratory test. The results of this study can be used to design, construct, Management and conservation provide a useful reference.
