反演理论在隧道及地下工程施工中的应用

On the Application of Reverse Inference Theory in Tunnel and Underground Engineering Construction

依据施工现场实测的应力、应变、位移等信息,反演确定地层的初始地应力及地层特性参数,据此对隧道及地下结构进行设计计算或校核检验,为确定围岩的支护形式、合理的支护时间和合理的结构设计提供便利与依据.

Auording to the information,such as stress,strain and displacement,which is obtained in construction site, the author makes the reverse inference to determine the original stress and the peculiarity parameter of stratum. Based on this, he designs, calculates and examines tunnel and underground structure, which provides convenience and basis for deciding supporting form of stones around them, reasonable supporting time and reasonable structural design.
