The bearing capacity of a foundation is often required to be detected in building design, and dynamic sounding is a novel method for detecting the bearing capacity of a shallow foundation, wherein the hammering energy (the product of weight of a heavy hammer and a drop distance) of the dynamic sounding is partially used for overcoming the penetration resistance of soil to a probe and is called as effective; the other part is consumed by the collision between the hammer and the feeler lever, the elastic deformation of the feeler lever, the friction between the feeler lever and the hole wall soil, the energy consumed by the plastic deformation of the foundation soil when the feeler lever passes through the hole, the energy consumed by the elastic deformation of the soil when the feeler lever penetrates the hole, and the like.

Assuming the hammering efficiency is η, the effective hammering energy can be expressed as tree-discussion η MgH, then: η MgH = Rd · a · e. In the formula: rd is probe unit penetration resistance; e, penetration per stroke; m is the mass of the hammer; h, a weight drop distance; g, a gravity acceleration; a is the cross section of the probe. When the through-man resistance Rd is used for determining the bearing capacity of the foundation, the through-man resistance Rd is divided by a coefficient for estimation.
