What is the unconfined compressive strength of type B soil?

Type B soil is classified as cohesive soil with a unconfined compressive strength that falls within a specific range. It typically has a unconfined compressive strength between 0.5 tons per square foot (TSF) and 1.5 TSF. This classification is important in excavation practices because knowledge of soil strength helps determine the appropriate safety measures when performing excavations.

Understanding the properties of Type B soil is essential for assessing risks associated with excavation work. Soil that falls within this strength range may require sloping or shoring to prevent cave-ins, ensuring worker safety. Recognizing that Type B soil is neither very weak nor particularly strong is crucial in planning and executing excavation safely.

Options reflecting strengths below or above this range would not align with the established classification criteria for Type B soil, ensuring that the recognized range of strength is properly acknowledged in excavation safety practices.
