Urban tunnel anti-floating calculation method and system based on multi-source design data fusion

Abstract

The invention relates to an urban tunnel anti-floating calculation method and system based on multi-source design data fusion. The method comprises the steps of obtaining multi-source data (overall data, geological survey data, road geometric design data and tunnel structure design data) for current urban tunnel project design; calculating parameter form standardization and data fusion processing; calculating working condition selection and main constraint condition determination (anti-floating water level and anti-floating stability safety coefficient); carrying out anti-floating stability checking calculation on the tunnel structure; carrying out special calculation aiming at anti-floating treatment measures; visualizing a calculation result by using a graph and a table; and outputting the main calculation result to a calculation book with a unified format. The method has the advantages of being good in user experience, high in calculation precision and high in speed, and the problems that manual calculation efficiency of traditional engineering technicians is low, errors are prone to occurring, and time and labor are consumed during reworking during design change can be effectively solved. The method is mainly applied to underground engineering such as urban open-cut tunnels, and is particularly suitable for tunnel engineering design of urban open-cut method construction.

Description

technical field [0001] The invention belongs to the technical field of urban tunnel engineering design, and in particular relates to an urban tunnel anti-floating calculation method and system based on multi-source design data fusion. Background technique [0002] With the development of my country's national economy and the deepening of urbanization, urban tunnel engineering, as an efficient traffic organization method, is being used more and more in the construction of urban traffic infrastructure. [0003] Urban tunnels, especially open-cut tunnels, face the problem of anti-floating stability during construction and operation due to their shallow buried depth. When the anti-floating stability does not meet the requirements of design codes and standards, special anti-floating design is required. At present, these design calculations are mainly completed by engineers and technicians relying on long-term accumulated design experience. Because multi-source design data is used...
