Similarity model test apparatus for simulating tunnel construction

Abstract

An embodiment of the present invention provides a similarity model test apparatus for simulating tunnel construction, comprising a testing stand, a hydraulic loading apparatus, a data test and acquisition apparatus, and a similarity model; wherein the hydraulic loading apparatus is arranged outside the testing stand; the similarity model is arranged inside the testing stand; one part of the data test and acquisition apparatus is arranged inside the testing stand, the other part of the data test and acquisition apparatus is arranged outside the testing stand. The similarity model test apparatus in the embodiment of the present invention not only can achieve simulation of an excavation process of the tunnel, a tunnel pre-support state and influence on the tunnel by extraneous dynamic load, but also can complete data acquisition and analysis through a built-in monitoring system, so as to evaluate and optimize deflection of tunnel excavation, control capability of support means, and influence degree on the tunnel construction by the extraneous dynamic load.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a similar model test device for simulating tunnel construction. Background technique [0002] With the sustained and rapid development of the national economy, underground traffic engineering is in full swing, and the construction technology of underground engineering has become a hot research topic in engineering circles at home and abroad. On busy main roads, underground passages have been opened; underwater tunnels have been built to cross rivers and seas; box culvert passages have been built when passing through railways and expressways; Normal take-off and landing, and the underground tunnel that crosses the airport runway is also being built under the strict requirements of non-stop flight. In order to better guide the smooth development of the project, a series of underground engineering construction simulation test devices that pass through existing buildings,...

AI Technical Summary

Problems solved by technology

In order to better guide the smooth development of the project, a series of underground engineering construction simulation test devices that pass through existing buildings, roads, railways, rivers and straits have been developed. At the initial stage, there is a lack of relevant research on the test device for the simulation of the construction process of the pipe-curtain pre-reinforced shallow-buried tunnel under the influence of dynamic loads.
