Description

Automatic calculation and design method for grouting reinforcement engineering quantity in rail transit tunnel Technical Field The invention relates to the technical field of rail transit, in particular to an automatic calculation and design method for grouting reinforcement engineering quantity in a rail transit tunnel. Background In the field of track traffic construction and maintenance, grouting reinforcement in tunnel holes is a key engineering technology for ensuring stable tunnel structure and preventing water leakage and stratum settlement. The calculation and design of the grouting reinforcement engineering quantity are accurately and efficiently completed, and the calculation and design are important for controlling engineering cost and guaranteeing construction progress. At present, a method for calculating and designing grouting reinforcement engineering quantity in a rail transit tunnel commonly adopted in the industry mainly depends on manual operation and experience judgment of a designer, and a typical flow and existing technical problems are as follows: 1) The automation degree is low, the efficiency is low, the whole process is highly dependent on manpower, and the steps from data extraction and parameter calculation to result summarization need to be performed by designers. In the face of tunnel intervals of tens or even hundreds of kilometers, tens of working days (for example, about 60 working days are needed for a certain subway project) are often needed for completing the whole-line engineering quantity calculation, and the design efficiency is severely restricted. 2) The calculation accuracy is difficult to ensure, a large number of manual operations and complex mathematical calculations are performed, so that risks of misreading, misrecording and calculation errors in the process are obviously increased, the accuracy of engineering quantity calculation is directly affected, and deviation can be caused to engineering budget and material purchase. 3) The digitization and intellectualization level is insufficient, namely design parameters are scattered in the drawing, and a structured digital asset cannot be formed and cannot be directly called and processed by a computer program. Any adjustment of the design scheme needs to manually re-execute the whole set of calculation flow, has high scheme iteration and optimization cost, and cannot meet the requirements of modern engineering on quick response and accurate design. 4) The labor intensity is high, and the resource waste is that the professional technician is bound in the repeated and mechanical data arrangement and calculation work, so that the labor resource is extremely wasted, and the design optimization work that the designer is focused on more creative is also influenced. Therefore, an automatic calculation method capable of realizing automatic parameter acquisition, intelligent calculation of key geometric parameters and one-key generation of engineering quantity is needed in the industry, so that the efficiency, precision and intelligent level of grouting reinforcement design work in a rail transit tunnel are fundamentally improved.
