Steep mountainous roadbed filling
When road routes pass through steep mountainous sections, using lightweight soil filling methods offers the following advantages: 1. Reduces load, minimizing the sliding moment of the subgrade, enhancing its anti-slip stability; avoids the high difficulty and cost of anti-slip design and construction of the subgrade.
Avoid the stability issues caused by excessive filling and the drawback of occupying a large amount of land resources.
3. Avoid the high costs of high边坡 support and environmental damage caused by excessive excavation.
