Description
Technical field
The present invention relates to tunnel structure laboratory test technical field, more particularly to a kind of Quantitative study tunnel surrounding comes to nothing
With the dynamic test device and method of softening.
Background technology
Due to tunneling technique, engineering method, formation condition etc., almost all of tunnel, which all exists, to be come to nothing and encloses in various degree
The problem of rock softens.The interaction between lining cutting and country rock will be seriously affected by coming to nothing and softening, and liner structure is caused locally to generate
Stress non-homogeneity even stress concentration phenomenon, can cause lining concrete to crack when serious, cause percolating water, freeze injury and reinforcing bar rust
A series of harm such as erosion, it is also possible to induce country rock relaxation or unstability falls off, sudden Collapse Accidents occur, to traffic quality and people
Member's life security constitutes a serious threat.Therefore, have to carrying out deep experimental study in the presence of the tunnel structure for coming to nothing with softening
Significance.
Currently, existing to come to nothing for tunnel structure and country rock the inspection that tunnel structure comes to nothing behind is concentrated on the patent of softening
It surveys and regulation, the tunnel as disclosed in Chinese invention publication number CN105044217A comes to nothing detecting head, tunnel void detector and inspection
The method that tunnel comes to nothing is surveyed, is hammered by building surface to tunnel double-lining, excitation tunnel double-lining concrete generates sound wave, passes through
The acoustic feature of vibrational waveform is picked up to judge whether tunnel double-lining comes to nothing and come to nothing degree, and devises corresponding tunnel and comes to nothing
Detector and detection method.The disclosed tunnel structures for regulation of coming to nothing of Chinese invention publication number CN203488189U lead to
It crosses back-grouting filling to come to nothing behind cavity, circumferential steel band is bonded new supporting construction with lining cutting, provides the peace of tunnel structure
It lays in entirely, bear later stage pressure from surrounding rock.
