Abstract | Grouting performance in the foundation treatment of khlong Tha Dan dam that is being constructed on undifferentiated volcanic rock was studied. The study included geological condition, work on first phase consolidation grouting of two main dam (RCC-B and RCC-S), some part of second phase consolidation grouting and curtain grouting. Cement take data were collected to compare with the geological condition i.e. RQD map, Lugeon map, rock mass classification and geological structure. High cement take was observed in faults, low RQD zones, high Lugeon value zones and poor rock condition area. Other than this area, low cement take was generally found due to tight joints and ve1tical joints orientation. Grout mix used at khlong Tha Dan dam is considered to be rather thick. The water pressure tests have been done after grouting in some area at the time of study. The evaluation of the dam foundation treatment in this research was performed on the basis of grout take statistic methods. The relationship of dam foundation grouting and the geological structure, Lugeon value and cement take, the joint system orientation and the curtain grouting plane was done. No clear relationship between Lugeon value and cement take at khlong Tha Dan dam was observed. Cement take was high in the primary and secondary grout holes and it decreased in the tertia1y and quaterna1y grout holes. Cement take was directly proportional to grout pressure. |
