Embodiment

[0032] Such as figure 1 As shown, a large-diameter shield tunnel face pressure estimation and management system based on BIM (Building Information Modeling) includes face management subsystem 1 and monitoring management subsystem 2. The main users of the face management subsystem 1 are the management personnel of the owner unit and the management personnel of the construction project department. The users are the management personnel of the owner unit and relevant scientific research personnel. They are used to monitor the operation of the tunnel in real time, record monitoring data such as tunnel deformation, and form data files for later scientific research work.

[0033] The model building method in the information model module 11 is: import the model information stored by BIM-related software into the system, and the system will perform intelligent modeling according to the BIM information. According to the system operation prompts, select objects such as the tunnel axis,...

Abstract

The invention relates to a BIM (building information modeling)-based management system for a tunnel face of a large diameter shield tunnel. The system comprises a tunnel face management subsystem which, according to project profile information, takes advantage of BIM technology to carry out informationalized modeling on the large diameter shield tunnel and conducts pre-estimation, setting and amendment on tunnel face pressure; a monitoring management subsystem, which carries out real-time monitoring and pre-warning on the construction of the large diameter shield tunnel, stores construction data, assesses engineering construction and management situation, and performs document management. Compared with the prior art, the management system combines classical tunnel face pressure pre-estimation theory with BIM technology, the pre-estimation and presetting of tunnel face pressure are completed before tunneling, and simultaneously, the preset pressure can be adjusted according to real-time monitoring results; and the stratum information, the tunnel face pressure information and surrounding environment deformation information are all integrated in a BIM model, and the visible and controllable whole construction process is realized.

Description

technical field [0001] The invention relates to the fields of safe construction and information management of large-diameter shield tunnels, in particular to a BIM-based large-diameter shield tunnel face management system. Background technique [0002] With its advantages of high efficiency, safety, and environmental protection, the shield method has been more and more widely used in the construction of major projects such as subways, urban water supply and drainage, railways, and highways at home and abroad since the 1970s. One of the main methods of tunneling. Although the development of the shield method has been relatively mature, under the poor hydrogeological conditions, the instability of the face of the large-diameter shield still occurs from time to time. In the process of large-diameter shield tunneling, it is very important to establish a mechanism for real-time feedback and adjustment of shield tunneling parameters, and to correctly understand the construction s...
