Embodiment 1
[0074] Such as Figure 1-Figure 10 As shown, the present embodiment is a shield tunnel construction early warning method for comprehensive urban building information and stratum structure, including the following steps:
[0075] Step 1, use the UAV to collect the urban surface image data in the target area, and then set the first control point;
[0076] Step 2, processing the surface image data obtained in step 1, processing the image to generate a point cloud model, and importing the coordinates of the first control point;
[0077] Step 3, collecting the drilling data of geological exploration on the site, and then importing the drilling data into modeling software to form a corresponding second control point;
[0078] Step 4, performing spatial interpolation on the second control point to establish surface models of different rock formations;
[0079] Step 5, establish a geological contour body, use Boolean operations to trim the rock formation surface, and use the rock fo...

The invention provides a shield tunnel construction early warning method integrating urban building information and a stratum structure. The shield tunnel construction early warning method comprises the steps of collecting earth surface image data, and forming a point cloud model; collecting on-site drilling data and importing into modeling software, and forming a second control point; forming different rock stratum entities, and forming a rock stratum contour model; highlighting key strata; collecting coordinates of a shield tunnel contour standard section and a tunnel center line, and generating a tunnel entity; establishing a geologic model cross section, and observing the relative position relationship between the tunnel and the key rock stratum and the ground building; performing early warning when the shield tunnel passes through key rock stratums and the positions below high-rise buildings on the ground, observing the numerical values of ground surface settlement, building settlement and segment settlement according to monitoring and measuring data, and formulating a multi-index grading early warning scheme to guarantee construction safety. According to the invention, the relative position relation between the mileage section of the shield tunnel and the dangerous rock stratum and the high-rise building is observed, a grading early warning scheme is formulated, and corresponding construction control measures are formulated in combination with the actual monitoring and measuring condition of each section and a refined geologic model.
Description
technical field [0001] The invention relates to the field of geological modeling, in particular to a shield tunnel construction early warning method that integrates urban building information and stratum structures. Background technique [0002] With the improvement of engineering informatization level, the development of computer visualization technology and the maturity of 3D geological modeling technology, 3D geological modeling has been widely used in fields such as energy, mines, urban underground space and traffic tunnels. 3D geological body modeling Refinement has become one of the research directions that modeling technology is paying more and more attention to at this stage. The real-scene 3D model building technology of UAV tilt photogrammetry is to carry multiple sensors (generally five-lens cameras) on a flying platform (such as a fixed-wing or rotary-wing UAV) to collect image information for data processing and modeling.
