Identifying the Hydrogeological Structure of Rock Foundation for Fill Dam by Pore Water Pressure Monitoring and Establishing the ICT Grouting Site Quality Control System

Abstract

An attempt for identifying the complex hydrogeological structure of rock foundation for fill dam by installing the pore water pressure gauge in rock layer, measuring its behavior during artificial change of underground water level with support of FEM analysis is reported. For evaluating the quality of curtain grouting and its in-situ impermeability before test reserving using installed pore water pressure gauge, ICT grouting site quality control system enabling the three-dimensional visualization including the relationship between pore water pressure behavior and grouting execution history is also introduced.
