3 dimension measuring and management system linked with construction simulation for tunnel and underground cavern}

The present invention relates to a three-dimensional integrated measurement management system in connection with a construction simulation system based on four-dimensional CAD (CAD) used in the process and progress management of tunnel and underground space construction work, more specifically in the tunnel and underground space site The user can manage and check the measurement information acquired from various measurement equipment installed in the system through the 3D VR (Virtual Reality) system conveniently and visually input / output and report the measurement information whenever necessary. The present invention relates to a three-dimensional measurement management system associated with underground space construction simulation.

In general, the construction of tunnels and underground spaces includes many indeterminate factors in the design due to the nonlinear behavior of the ground, the constraints caused by reproducing the field situation in the laboratory, and the technical limitations of various investigations and experimental methods. Therefore, the problems caused by these uncertainties in the design stage are found during construction and operation, and fed back to the design and construction to perform site measurement in various ways for the purpose of securing construction stability and economic feasibility.

In particular, as the construction of tunnels and underground spaces has become larger and more complex, the types and amounts of various measurement data on the site have increased greatly. Therefore, there is a need for a user to conveniently store and manage a large amount of measurement data. .

The existing measurement management system developed to date has been developed with a focus on the acquisition, transmission and storage of measurement data. Korean Patent Registration No. 10-0734071 proposes a civil measurement ubiquitous informatization system using a portable measuring device, which means the construction of a measuring device and information system for rapid analysis and safe construction of site measurement in the measurement management of civil construction sites. In another Korean Patent No. 10-0384933, real-time civil engineering measurement management using a network that monitors various construction conditions by automating the overall system related to civil engineering measurement and manages measured information from remote sites connected through the internet network. The system is proposed.

However, in the above-described conventional measurement management system, the database of the instrument location information and the measurement information is configured to be managed only on the serial number method or the two-dimensional plane, and thus there is a limit to the user effectively utilizing the measurement information.

In particular, during the construction of tunnels and underground spaces, geological conditions vary depending on the spatial distribution, so the installation location, interval, and measurement frequency of the instrument are variable. Therefore, the instrument installation location is not regularly arranged at predetermined intervals before construction, and may be concentrated in an area showing poor geological conditions so that the user installs the instrument according to the situation during construction. It must be able to visually determine and confirm the position on the virtual reality (VR).

In the construction process management simulation field, PERT / CPM or Bar- is designed to grasp the construction schedule and its progress according to construction type by visualizing plan data visually using a line graph or bar graph. Process control chart by chart is widely used as process control method. Two-dimensional process table by PERT / CPM or Bar-Chart is suitable to be used for correlation logic or simple schedule management level, and to grasp construction condition of site and design interference between equipment and actual photographing scale. It was difficult to do.

On the other hand, the three-dimensional architectural model using 3D CAD (Computer Aided Design), by presenting the spatially three-dimensional representation of the building can present more realistic and concrete data for the structure. At this point, however, these three-dimensional architectural models are simply created for the purpose of designing the building to be used to check the design interference between the equipment or to be used as a presentation material for an overview of the construction project. In other words, although the design implemented through 3D CAD has advantages such as inter-device interference, feasibility review, and BM calculation, the data that can be obtained is merely a concept that does not reflect the site situation. The specific construction schedule, such as the time required to build the model, was not taken into account, and its usability was limited.

In order to overcome this problem, Korean Patent Registration No. 10-0593716 combines the three-dimensional visual data and the two-dimensional time management system for the construction status of the building and the relationship between the construction status and the site performance and work. A four-dimensional construction process management system has been proposed for visual identification.

The patent proposed above is a construction process management system based on 4D CAD (4D CAD). Unlike general CAD and video simulation, the existing construction schedule and 3D drawing are linked to the completion state of the facility according to the construction period. It is a technology that implements 3D continuously, and time and 3D design space of the process table are integrated.

The conventional four-dimensional construction process management system has the advantage of determining the error of the process level early, the user can visually easily check the construction status and performance. However, it is difficult to apply the 4D construction process management system in the tunnel and underground spaces because of the characteristics of the structure, and the installation of the measuring instrument was not considered in the construction design. It is assumed that it is arranged and installed to reflect the design construction.

This design construction cannot reflect the case where the instrument is intensively installed in tunnels and underground spaces with poor geological conditions, and the installation location or spacing of the instrument in tunnel and underground construction works where the geological conditions differ depending on the spatial distribution. In other words, it is difficult to check the location of the instrument directly installed in the field according to the variable measurement frequency. These problems include the uncertainty and risk factors of the ground environment, which can impair the stability of the construction, and also have the problem of difficulty in selecting the optimal construction alternative.

Accordingly, the present invention has been proposed to solve the above problems, and provides information and measurement data related to various measurement equipment obtained during the construction of tunnels and underground spaces, which have high risks of uncertainty and construction and maintenance of the ground. It is applied to the 3D VR system to enable visually effective measurement management, and by linking the measurement management system with the 4D CAD-based construction process management system, the optimal construction alternative is selected during construction. The purpose is to provide a three-dimensional measurement management system linked with tunnel and underground space construction simulation that can reduce the cost and establish a reasonable construction plan.

In order to achieve the above object, the present invention provides a measurement information management module including a registration, modification, and deletion function of the measuring instrument and reference and reference data related to the measuring instrument; Input the installation location data of the instrument to the construction simulation based on the 4D model linked to the work breakdown structure (WBS) and the three-dimensional drawing, and display the installation location of the instrument in the construction simulation in three dimensions. 3D (dimension) measurement information module comprising a; And 3D measurement management system in connection with tunnel and underground space construction simulation including measurement status information module which inquires comprehensive information of measurement status and inquires status and report of measurement equipment applied to the whole section.

As described above, according to the characteristics of the present invention, the measurement management is performed on a three-dimensional virtual reality (VR) by escaping from the existing measurement management system that only considers the planar measurement information. It is effective in providing visual and efficient basis when determining management techniques during construction in connection with process management construction simulation.

In addition, it is possible to develop future cost analysis in the tunnel and underground space construction areas, and to prevent risks through the risk evaluation algorithm considering the uncertainty and risk factors of the ground environment and to suggest the optimal construction method. There are other effects that can be.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The three-dimensional measurement management system in connection with the tunnel and underground space construction simulation according to the present invention manages the measurement information of various measuring equipments in the construction site or after construction by combining the three-dimensional construction simulation with a local method to make a decision. It is implemented to provide quick and clear guidance, and in particular to provide visual information on measurement information and various report information linked with it.
