Partition detecting method and device for flyover crossing tunnel construction

Abstract

The invention discloses a partition detecting method and device for flyover crossing tunnel construction. The partition detecting method comprises the steps that first data are received and comprise surrounding rock classification, the crossing angle and the crossing clear distance; the displacement criterion value of a position, to be detected, on a first tunnel is obtained according to the first data; the calculated displacement criterion value of the position to the detected is compared with a pre-stored partition reference value, and the partition classification of the position to be detected is determined. The first data are received, the displacement criterion value of any detected position of the first newly-built tunnel is calculated, the displacement criterion value is compared with the pre-stored partition reference value, therefore, the partition classification of any position of the first tunnel is determined, the interaction degree of flyover crossing tunnels can be quantized conveniently before the flyover crossing tunnel construction, selection of a tunnel supporting structure and a tunneling construction method is guided, and the safety and reliability of the construction are guaranteed.

Description

technical field [0001] The present invention relates to the field of tunnel construction, in particular to a partition detection method and device for the construction of multi-level intersection tunnels. Background technique [0002] With the development of our country's national economy, the demand for infrastructure, especially for the construction of transportation facilities, is constantly increasing. At the same time, high-level traffic arteries have also been developed unprecedentedly. For example: high-speed / heavy-haul railways and expressways are the main development directions of land transportation such as railways and highways respectively; the construction of urban subways and urban underpass tunnels is an important means to ease urban traffic; With the vigorous development in the development, the construction of diversion tunnels appeared in large numbers. With the increasing demand for construction of tunnels and diversion tunnels for railways and subways, it...
