T/HNKCSJ 009-2023 Slope engineering technical standards
Basic Information
Scope
Scope: This standard applies to slope projects with a height of less than 40m (including 40m) for rock slopes, and a height of less than 20m (including 20m) for soil slopes, as well as rock foundation pit slope projects. For slope projects exceeding the above-mentioned height limits, thorough justification and specialized design are required. Main technical content: The main content of this standard includes: 1. General provisions; 2. Terminology and symbols; 3. Basic requirements; 4. Slope engineering investigation; 5. Lateral geotechnical pressure of slope support structures; 6. Slope ratio method; 7. Gravity retaining walls; 8. Cantilever and braced retaining walls; 9. Reinforced soil retaining walls; 10. Anchored plate retaining walls; 11. Soil nail walls and composite soil nail walls; 12. Anchors; 13. Rock spraying support; 14. Anchored plate retaining walls; 15. Grid-anchored rods; 16. Pile-plate walls; 17. Pile-anchored plates; 18. Combined support; 19. Slope protection and greening; 20. Drainage projects; 21. Slope projects with important buildings (structures) at the top; 22. Landslide prevention and control; 23. Slope engineering construction; 24. Quality inspection, testing, and acceptance of slope engineering projects.
