AI Technical Summary

Technical Problem

Existing technologies lack systematic and efficient methods for statistical analysis of the through-structure surfaces within the dam foundation rock mass based on borehole television data, resulting in a large workload and low efficiency.

Method used

A plane rectangular coordinate system was established with the dam axis as the reference. By combining dip angle conversion and profile projection, the structural surfaces with different attitudes in the borehole were classified and statistically analyzed using in-hole television technology. The dip and dip angle parameters were used to divide the rectangular coordinate system into four quadrants to identify potential through structural surfaces.

Benefits of technology

It enables efficient and intuitive statistical analysis of the internal continuous structural surfaces of the dam foundation rock mass, providing direct geological basis for the analysis of the dam foundation's anti-sliding stability and improving the efficiency and accuracy of the analysis.

Abstract

This application discloses a statistical method for studying the development of interconnected structural planes within dam foundation rock masses, enabling efficient statistical analysis of the interconnected development of structural planes in deep dam foundation rock masses. Structural planes within dam foundation rock masses are a key factor in analyzing their anti-sliding stability, and the degree of microcrack penetration directly affects the type of dam foundation slip and the selection of anti-sliding stability calculation methods. This invention employs borehole television technology to statistically analyze structural planes in boreholes, distinguishing structural planes with different attitudes to obtain the distribution of dominant structural planes at different depths within the rock mass. Furthermore, by systematically evaluating structural planes in boreholes at different locations, the development characteristics of interconnected structural planes within the dam foundation rock mass are clarified. This method is intuitive, rapid, and efficient, providing an effective technical means for dam foundation rock mass stability analysis.
