This specification is applicable to slope engineering of buildings (structures) and municipal engineering, and also applicable to rock foundation pit engineering. For soft soil, collapsible loess, frozen soil, expansive soil, other special rock and soil and slopes in erosive environments, they should still comply with the current relevant standards. The building slope height applicable to this code is less than 30m for rocky slopes and less than 15m for earthy slopes. For slope engineering exceeding the above-mentioned height, slope engineering with complicated geological and environmental conditions shall be specially designed.
