What is the slope ratio of type B soil?

Type B soil generally has a slope ratio of 1:1, meaning that for every one unit of vertical rise, there is one unit of horizontal run. This representation indicates a steep but manageable incline for excavation and structural stability purposes. Understanding the properties of type B soil is crucial for ensuring safety during excavations, as it typically has a greater stability compared to type C soil but requires caution in managing its slope.

In the context of soil classifications, type B soils include materials like stiff clay, sandy clay, or materials that possess good cohesion. Having the correct slope ratio is vital for maintaining the integrity of excavations and minimizing the risk of cave-ins. Choosing a slope that is too steep can lead to increased stress on the soil structure and compromise safety.

Realizing the differences in slope ratios for varying soil types, like the more gradual slopes of type A or the steeper ones of type C, provides a clearer understanding of how to approach excavations safely and effectively.
