The Application of New Blasting Technique on the Replacement of Soft Silt Foundation by Rock Filling

Abstract:

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.
