摘要
研究目的:本文结合郑西客运专线大断面黄土隧道一秦东隧道这一工程实例,针对砂质黄土变形特点和大断面黄土隧道不同的施工方法,就如何选择合理的量测项目、量测频率和量测方法进行了阐述,以求掌握大断面黄土隧道的变形规律。研究结果:结合秦东大断面黄土隧道的施工实践,得出了大断面黄土隧道拱顶下沉、水平收敛等项目的变化规律,对黄土隧道施工起到良好的指导意义。
Research purposes:This paper based on the engineering example of large section loess tunnel of Zhengzhou-Xi an passenger dedicated line,focuses on distortion features of the sandy loess and the different constructions methods of large section loess tunnel,illustrates the method for how to choose the reasonable measuring project,measuring frequency and measuring methods,analyzes the measuring data to master the deformation regulation of the large section loess tunnel. Research results:Combining the construct...
