Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1~2 As shown, a secondary lining arch foot settlement experiment loading device includes a secondary lining 1 and a trench 12, and the secondary lining 1 includes two bases 5 and an arched structure 15 between the two bases 5, One of the bases is consolidated with the trough 12, and the other base and the trough 12 are driven by a settling device to carry out load application and deformation settlement at the end of the arched structure. The surface of the arched structure 15 is provided with a Displacement and deformation monitoring system for monitoring node displacement values ​​and element strain values.

[0026] In this embodiment, the settling device includes an upper steel plate 11 and a lower steel plate 14 placed horizontally up and down, a number of springs 10 are fixedly connected between the upper steel plate...

Abstract

The invention relates to a secondary lining arch foot sedimentation experiment loading device. The device comprises a secondary lining and a geosyncline. The secondary lining comprises two pedestals and an arc structure located between the two pedestals. One pedestal and the geosyncline form solidification. The other pedestal and the geosynclines are driven by a sedimentation device so as to carry out load applying of an arc structure end portion and deformation sedimentation. A surface of the arc structure is provided with a displacement deformation monitoring system used for monitoring a node displacement value and a unit strain value during the load applying. The secondary lining arch foot sedimentation experiment loading device can solve a condition that sedimentation exists at an arch foot in a research during mountain tunnel secondary lining. Construction is convenient, operation is simple and the device is economical and practical.

Description

technical field [0001] The invention provides a secondary lining arch foot settlement experiment loading device and a using method thereof, which belong to the technical field of tunnel research. Background technique [0002] Since the reform and opening up, with the rapid development of the national economy, my country's highway construction has also flourished, especially the construction of high-grade highways is changing with each passing day, and the national high-grade highway network pattern is taking shape. Due to the high linear technical indicators of high-grade highways, when they enter mountainous or heavy hilly areas, it is inevitable to use tunnels to cross mountains and ridges. Therefore, driven by the rapid development of high-grade highways, highway tunnels, which are an important part of highways, have also ushered in an unprecedented construction boom. However, with the increase of the service life of the completed tunnels, most of them have different deg...
