Connect an A-drill … WebIntroduction The unit weight, also known as the ‘weight density’, of a soil refers to its weight per cubic metre and is typically expressed as kilonewtons per cubic metre (kN/m3), or tons per cubic metre (t/m3)1. Knowing the unit weight of a soil is particularly important for geotechnical design, as well as assessing earthworks volumes.

WebOne of most common methods for determining allowable soil bearing capacity is from standard penetration test (SPT) numbers. It is simply because SPT numbers are readily available from soil boring. The equations that are commonly used were proposed by Meyerhof based on one inch of foundation settlement.
