| Abstract: | With the ultra sonic wave probe, a research of test and measurement on the variation of consolidation time for grouted soil in soil strata was conducted. The soil materials are fine sand and sandy soil. The grout is a cement and sodium silicate double grout. Base on the wave velocity, from the variation law with the consolidated time passed. It can be know that after 4 days of the grouting operation, the soil mass would have a stable consolidated strength. |
