Abstract:

The construction of underground works has become larger and larger in scale, which renders high requirements on construction methods and on construction monitoring and measurement. Monitoring and measurement can visually reflect the stability of the surrounding rock mass and the structures, and monitoring analysis can be used to modify construction support parameters so as to achieve informationaided construction. During the construction of a tunnel, the water inflow rate, surrounding rock displacement and crown settlement are measured, and information analysis and feedback are timely conducted, which provides the theoretical basis for the informationaided construction of the tunnel. In the end satisfactory results are achieved.

Key words:  , underground works  , construction monitoring and measurement informationaided construction
