摘要
在实际公路施工中,应该对路基沉降进行详细监测,并加强超前支护,以此来控制地层位移,避免地对围岩产生扰动,避免发生路基沉降,提升公路施工质量管控效果。以雪峰山高速公路路堤隧道施工项目为实例,将介绍基于公路路堤下隧道所致路基沉降的施工质量管控问题,分析路基沉降的原因,并制定优化的施工质量管控决策,该方案在实际公路项目中得到了应用验证。
In the actual highway tunnel construction process, should conduct a detailed monitoring of the subgrade settlement, and strengthen the advance support, in order to control the displacement of surrounding rock strata, avoid the disturbance, avoid the occurrence of subgrade settlement, improve high- way construction quality control effect. In this paper, the construction project of a highway embankment tunnel as an example, introduces the construction quality control of highway embankment caused by tun- neling under the roadbed settlement based on the analysis of the reasons of subgrade settlement, construc- tion quality control and make decision optimization, this scheme has been verified in actual highway pro- ject.
