龙头山特大断面公路隧道流变模型辨识(英文)

Rheology Model Identification about Longtoushan Large Section of Highway Tunnel

基于室内土样的流变试验结果和现场监控量测数据,结合岩土流变本构理论,并参考相关工程资料,对龙头山隧道洞口段V级围岩、洞身段II～IV级围岩的流变模型进行了辨识,为系统进行龙头山隧道工程的流变效应研究奠定了基础。

Based on the reheological indoor test results of soil samples and on-site monitoring measurement data, combined with rock rheological constitutive theory, and taking into account relevant information on the project,reheol- ogy model of the Ⅴ grade rock on the starting of longtoushan tunnel and that of the Ⅱ - Ⅳ grade rock of longtoushan tunnel are identified, laying the foundation for the reheology characterastic study of the project of longtoushan tunnel.
