Using of Microgravity Technique to Determine the Cavities and Weak Zones, and Treatment Methods in the zone of Foundations of Dijlah Hospital, Tikrit, Iraq

Abstract

Lacoste & Romberge model D-198 microgravimeter was used to investigate the microgravity data, the required corrections were done to construct the map of Bouger anomaly which leads to determine the depths, extensions, and shapes of cavities and weak zones along selected traverses under the foundations of Dijlalah hospital. The materials of grouting, as well as, the conditions of grouting were determined.
