Analysis of Experimental and Estimated Jet-Grouted Soil Mass Deformations

摘要

The use of technology jet grouting soil for the device of vertical geotechnical barriers widespread currently. The arrangement of jet elements in the plan may be single-or multi-row, contiguous or split version. The choice of the solution depends on specific geological conditions of the site. The design of the geotechnical barrier, made of jet elements, is reduced to the calculation of strength and reliability assessment of the structure. Principles of the purpose structural design are based on the theory of reinforced concrete and experimental data on testing of samples of materials. The purpose of this paper is to study methods to improve geotechnical subgrade-fix jet grouting, and the selection of the most simple and applicable mathematical model for the calculation.
