AI Technical Summary

Technical Problem

In existing railway alignment design, the methods for quantitatively evaluating geological disaster risks cannot effectively reflect the spatial heterogeneity within geological disaster risk zones and the spatial guiding effect of risk sources on the alignment, resulting in insufficient protection or over-design. Furthermore, these methods rely on subjective experience, leading to significant discrepancies between the quantitative results and the actual situation.

Method used

A method for quantitatively calculating the risk potential energy of railway alignment is adopted. Through CGIM grid division, risk source parameter database construction, risk unit distance calculation and repulsion force synthesis, the risk potential energy of the alignment grid is quantified. Combined with the penalty coefficient, the alignment is optimized, thereby improving the accuracy of risk quantification and the precision of engineering design.

Benefits of technology

It improves the accuracy of geological disaster risk quantification, dynamically guides route optimization, avoids insufficient protection in the core area or over-design in the peripheral area, reduces project investment, and improves the accuracy of risk quantification and the fit of project design.
