Abstract
Portland cement, superfine cement and modified sodium silicate have been taken as grouting materials in the aeolian sand tunnel which is characterized by single particle, bad gradation and loose structure. In this paper, penetration grouting and rotary jet grouting have been adopted in site grouting experiment, whose effects are tested by excavation sampling test and field excavation detection. The grouting feature of aeolian sand formation has been revealed. In the meantime, the applicability of different kinds of grouting materials in aeolian sand tunnel have been clarified which provides useful significance and reference value on the selection of grouting parameter and construction in aeolian sand tunnel.
