本文依托西部某高速公路填方路基工程,采用剖面沉降仪,对路基剖面沉降进行了长期监测。本文详细介绍了剖面沉降管的布设工艺与监测方法,研究了路基剖面沉降规律,认为对数曲线较好的描述了路基剖面沉降基本规律。并针对研究结论提出了相应建议,为填方路基的施工提供参考。 This paper relies on a highway subgrade project in western part of China, and adopts profile settlement meter to conduct long-term monitoring of subgrade settlement. In this paper, the laying process and monitoring method of profile subsidence pipe are introduced in detail. The settlement rule of subgrade profile is studied. It is considered that the logarithmic curve describes the basic law of subsidence of subgrade profile. And some suggestions are put forward for the conclusion of the study, which provides reference for the construction of roadbed filling.
