The Application of New Blasting Technique on the Replacement of Soft Silt Foundation by Rock Filling
Based on the limit analysis equilibrium theory for the soft soil foundation under rock filling load, a new blasting technique is developed on the main mechanism to soften the strength of soft silt and to relieve the inside pressure of different kinds of soft soil, and a set of design method of blasting destressing is proposed to replace soft silt by rock filling. This technique is applied in the rock filling embankment of a waterfront airport project, which makes a breakthrough to the designed application limit of the current technical codes and acquires a favorable effect of replacement by rock filling.
