Problems solved by technology
Due to the high pressure of air traffic, the construction of the airport will not interrupt the operation of aircraft, so it is difficult to carry out continuous construction
Most of the non-stop construction is intermittent assault operations at night, it is often difficult to conduct a comprehensive monitoring of the entire construction process, and there is a lack of evaluation methods for its impact on flight safety

Embodiment
[0056] The embodiment of the present invention provides a method for digital modeling and impact estimation of non-stop construction of airport pavement, which mainly includes the establishment of a three-dimensional digital model of airport pavement based on BIM and the development of a probability model of flight safety impact under the situation of non-stop construction .
[0057] Further, the specific steps of the process are as follows:
[0058] (1) Based on the specific airport roads, combined with satellite maps and existing airport data, the AutoCAD drawing process is performed on the two-dimensional plane of the airport to obtain the appearance of the airport. The airport pavement is divided into blocks using the actual pavement block of the airport or referring to the PCI (pavementcondition index, pavement condition index) to minimize the impact of detection.
[0059] (2) Organize the key information such as the plane size of the road slab in each area of the airp...

The invention provides an airport pavement non-stop construction digital modeling and influence estimation method. The method comprises the following steps: (1) drawing an airport two-dimensional plane CAD drawing based on an airport drawing, a satellite map, airport data and the like; (2) dividing airport pavement plates, and classifying the pavement plates based on the size, structure and material information of the pavement plates in each region of the airport; (3) according to the size, structure and material information of each pavement plate, creating a Revit loadable family for the regular pavement plates, adjusting system floor parameters for the irregular pavement plates to meet the actual structural layer condition of the irregular pavement plates, placing the pavement plates by taking a two-dimensional plane CAD drawing as a base drawing, and establishing an airport three-dimensional model; (4) carrying out real-time dynamic video monitoring on the non-stop construction area, regularly capturing video images and developing a background difference pre-screening algorithm to carry out overall change condition analysis on the construction area; and (5) carrying out airport pavement non-stop construction influence evaluation.
Description
technical field [0001] The invention belongs to the field of simulation of the impact of airport pavement non-stop construction on flight safety, and in particular relates to a method for digital modeling and impact estimation of airport pavement non-stop construction. Background technique [0002] Non-stop construction at an airport refers to the construction work carried out in the terminal area and flight area when the airport is basically operating normally, that is, when the airport still receives and releases aircraft according to the flight plan. Non-stop construction in the airport flight area is a routine event in airport reconstruction and expansion projects and daily maintenance management. Due to the high pressure of air traffic, the operation of aircraft will not be interrupted during airport construction, so it is difficult to carry out continuous construction. Most of the non-stop construction is intermittent assault operations at night, and it is often diffi...
