基于现场测试的软弱黄土地基桥头引道路堤变形规律及控制措施研究

Study on Deformation Law and Control Measures of Embankment in BridgeApproach Based on Field Test

基于现场测试手段,深入研究分析软弱黄土地基桥头引道路堤变形的时空特征,并从技术方面系统提出变形控制技术措施,确保桥头引道的工程质量。通过现场观测,分析各类技术手段对桥头引道路堤变形控制的有效性。

Based on the field tests, the spatial and temporal characteristics of the bridge approach embankment deformation on the weak loess foundation were studied;in addition, the deformation control technology was proposed from a technical point to ensure the project quality of the bridge approach. The validity of each technology to control the deformation of the bridge approach embankment was analyzed by the field tests.
