Embodiment 1
[0074] like 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 forma...

The invention provides a shield tunnel construction early warning method integrating urban building information and stratum structure: collecting surface image data to generate a point cloud model; collecting on-site drilling data and importing it into modeling software to form a second control point; generating different rock strata entities , form a rock stratum profile model; highlight key rock strata; collect shield tunnel profile standard section and tunnel centerline coordinates to generate tunnel entity; build a geological model cross section to observe the relative positional relationship between the tunnel, key rock strata and ground buildings; cross key points in the shield tunnel Early warning is provided under rock formations and high-rise buildings on the ground. According to the monitoring and measurement data, the values of surface settlement, building settlement and segment settlement are observed, and a multi-index graded early warning scheme is formulated to ensure construction safety. The invention observes the relative positional relationship between the shield tunnel mileage section and dangerous rock formations and high-rise buildings, formulates a graded early warning scheme, and formulates corresponding construction control measures in combination with the actual monitoring and measurement conditions of each section and the refined geological 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. [0003] Existing technology: Chinese I...
