Description
Technical Field
The invention relates to the technical field of tunnel construction, in particular to a classification method for judging and improving tunnel surrounding rock grades of an FMC model based on rock sensitive parameters.
Background
In tunnel construction, the real-time accurate sensing of the surrounding rock state of the tunnel face has important significance for dynamically adjusting tunneling parameters, reasonably adjusting a tunneling scheme and avoiding engineering risks for a TBM main driver. The adjustment of the existing tunneling parameters mainly depends on the experience control of a TBM main driver, once the surrounding rock state identification is inaccurate or stratum mutation is encountered, if the tunneling parameters and schemes are not adjusted in time, major engineering accidents such as blocking, collapse and the like can be caused, and major economic loss is caused. For example, in TBM construction of a highway tunnel on a Kunming palm dove river diversion water supply project, due to inaccurate judgment of surrounding rocks and unreasonable tunneling parameters, the surrounding rocks are greatly disturbed to cause a blocking accident, and the time for escaping treatment is 3 months; the south TBM section of the engineering Ringnan of Hanjiwei meets a high-abrasion granite stratum suddenly, so that a large number of hobs are abnormally abraded, and the average tunneling life of the hobs is only 2.46 m; the hydraulic tunnel of the south Africa Lyocell meets basalt with high hardness and high quartz content due to geological mutation, and the tunneling main control parameters are not adjusted in time, so that the whole disc of cutters is scrapped, and the tunnel is stopped and overhauled for 2 months. The existing TBM tunnel face surrounding rock identification is mainly based on geological survey data and tunnel face advanced drilling coring, the traditional method has certain limitation, the geological survey data is that the engineering geology of the whole line is known roughly, the surrounding rock classification is only roughly described, the specific surrounding rock classification of a certain pile number cannot be given in detail, and the limitation is more obvious in tunnel construction in large buried depth, long distance and extremely complex environment. The tunnel face surrounding rock identification in the special section by advance drilling and coring on the tunnel face surrounding rock not only influences the tunneling continuity, but also cannot realize the advance and real-time performance of the information acquisition of the tunnel face surrounding rock, and cannot meet the requirement that a TBM main driver dynamically adjusts the tunneling main control parameter according to the tunnel face surrounding rock grade change. Under the background, the surrounding rock grade of the tunnel face of the TBM is judged and perceived in real time, and surrounding rock grade state information capable of being perceived according to rock sensitivity parameters is searched.
In the research aspect of a surrounding rock identification method, patent retrieval comparison shows that Qinghua university invents a test method for quantifying the surrounding rock grade, and the patent number is as follows: 201610437798.5 ", Beijing City construction survey design research institute, Inc. invented" an assessment method for obtaining comprehensive surrounding rock grade from upper and lower layers of surrounding rock grade, patent number 201710577849.9 ", and Zhongxie engineering Equipment group, Inc. invented" a TBM in rock mass excavation state real-time sensing system and method, patent number 201710761045.4; an intelligent decision-making method and system for hard rock TBM tunneling control parameters, patent number 201710937469.1; a method for obtaining a surrounding rock category based on slag slice image identification, patent No. 201810019670.6; an online surrounding rock quality grading method based on a PSO-SVM algorithm and image recognition is disclosed in patent No. 201910769555.5 ', Guangxi road and bridge engineering group Limited company, which discloses a surrounding rock grade prediction method based on TSP forecast data and an XGboost algorithm, patent No. 202110242796.1 ', southwest traffic university, which discloses a method for recognizing the surrounding rock grade, patent No. 202011155747.6 '. The current situation of surrounding rock identification is combined, and the comparison of the patents shows that:
(1) in the existing stage surrounding rock identification method, the state of the front rock mass is comprehensively evaluated according to the physical characteristic parameters of the rock mass, the image identification of the rock slag of the tunnel boring machine and the advanced geological forecast parameters, and the number of rock machine parameters related to the TBM is small.
(2) The physical characteristic parameters of the rock mass cannot be obtained in real time, the promptness and the real-time performance of the information acquisition of the surrounding rock of the face cannot be realized, and the requirements of a TBM driver for dynamically adjusting the tunneling parameters and the tunneling scheme according to the grade change of the surrounding rock of the face cannot be met.
