Dam core conditions are important to check its safety regularly. One way to determine the condition of a dam is to compare the pore-water pressure upstream to downstream. If the upstream pore-water pressure is higher than downstream, the dam is in good condition. The pore-water pressure at the dam is got from the piezometer planted inside the dam. If the piezometer is damaged, the condition of the dam's core is unknown. In Lahor dam there are 18 piezometers, but only one was functioning. The pore water pressure of the piezometer is determined by the height of the water column above it so that if the water level is known in the dam core, the pore water pressure will be known. To find out the water table, georadar can be used using a B-scan survey technique along the Lahor dam. The radargram is then processed to get the type of material by finding the wave velocity regarding the water level at the upstream of the dam. The water table is obtained from reflections of anomalous material differences. The water table converted into pressure based on piezometer level. From the results of pore water pressure in upstream and downstream, it can be concluded that the Lahor dam is in good condition. [ABSTRACT FROM AUTHOR] |
