Construction Monitoring And Control Of Road Multi-arch Tunnel

Multi-arch tunnel, as a new topic in our country, was still the stage of existence and verifying the legitimacy, and the study has been pointing any specific question. Combing the present needs of construction and monitoring measurement of tunnel, the something, including the design, content, practice of using, data processing of safety monitoring measurement, was formulated and studied, on the basis of the technology of monitoring measurement and theoretical study of road tunnel which was done by our predecessors. Through an example of Longshan tunnel, be in Wuhu, Anhui Province, which was a shallow large-span duel-linked arch. The measurement data of partial physical quantity taken from construction were analyzed and predicted for the aims of construction control, and the result of analysis was feed backed to tunnel construction and design. To guide informational design and construction of duel-linked arch tunnel, further, to dynamics control of tunnel construction environment and influence to surrounding, the analysis about stimulation and dynamic of construction, at the same time, including construction influence to surrounding, was done. The study of construction stimulation and control of multi-arch was run to solve tunnel dynamics construction mechanics.
