Abstract

The earth pressure shield method can be applied to various kinds of soil, but a certain countermeasure is needed to prevent the gush of water at the gate of soil removal with excavating some types of soils such as granular soil.<br>The “Silica shield method” uses silica jelly as an additive to solve the above mentioned problem.<br>This report describes the various effects of silica jelly such as improvement of fluidity of excavated granular soil, the optimum mixing ratio of silica jelly and the safety features.
