Database-based railway mountain tunnel construction organization design method

Abstract

The invention discloses a database-based railway mountain tunnel construction organization design method, which comprises the following steps of: respectively establishing construction progress index databases for different types of railway mountain tunnels; inputting applicable mileage ranges of different construction progress index parameters in the technical standard; reading construction parameters of the main tunnel and the auxiliary tunnel; matching and generating a construction progress index of the construction of the auxiliary tunnel, and calculating the construction time of the auxiliary tunnel; matching and generating a construction comprehensive information table of the main tunnel; dividing work areas, generating a work area information table, and generating an effective work area group table; calculating the through mileage, the through construction period and the total construction period of each work area; a calculation result is extracted, and a construction organization information table is generated; and generating fixed format data convenient for drawing a tunnel construction organization diagram. The intelligent design of the construction organization of the railway mountain tunnel under various combination conditions is realized. The design difficulty is reduced, the design efficiency is improved, the universality is high, and the flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of railway mountain tunnel design, in particular to a database-based construction organization design method for railway mountain tunnels. Background technique [0002] The construction organization design of the railway mountain tunnel is an important link in the design of the railway mountain tunnel, which plays a key role in the comparison and selection of the scheme and the control of the construction period. When using the traditional design method, the designer needs to manually select the construction progress indicators of each section of the main tunnel and auxiliary tunnel one by one, and cooperate with manual calculation. The total construction period can be calculated after drawing a map. The traditional design method has three shortcomings: first, the design process is cumbersome, the repetitive workload is large, and the later modification workload is large; second, the design speed and efficie...

AI Technical Summary

Problems solved by technology

There are three shortcomings in the traditional design method: first, the design process is cumbersome, the repetitive workload is heavy, and the later modification workload is heavy; second, the design speed and efficiency are low; third, human matching errors are prone to occur

[0003] None of the currently known auxiliary design systems for railway tunnels can realize the intelligent design of construction organization. They can only complete the simple matching and design of construction progress indicators in a specific situation, and cannot consider the construction direction of entrance and exit, the construction direction of auxiliary tunnels, and the construction of openings. Combination of multiple factors such as preparation period, winter break period, construction period of roof-lifting, secondary lining lag, secondary attack direction lag, etc.
