| Abstract | Fist preparations of the Ban Mong reservoir project started 38 years ago by preliminary field investigation during the Vietnam War. The main obstacles of the project construction were the poor traffic systems and leak of big investments. The studies of the project investigation were renewed in 2003 and 2007 with the assertion of the feasibility project. Two design options were suggested for a more in-depth investigative study. This detailed design study applied the new combined geological engineering methods to investigate the complicated conditions of the geological structures of the project ares. THe combination of geophysical and geotectonic investigations was used in this study to select the realizable design option. From August 2009 to May 2010 The field engineering geological investigation had been conducted over an area of 160 ha for the headwork. A total of 120 boreholes were drilled with various depths from 18m to 60m. The rock core samples were collected from 85% to the full depth range at each borehole. The laboratory tests including thin section analysis, rock index properties (water content, density) and rock strength (uniaxial compressive strength, Brazilian tensile test, modified direct shear test. In the field, the Lugeon test was conducted to 3 sections of each borehole. Based on field observation and testing results an engineering geological map of 1:2000 scale was made for the headwork area. As a result of this study, the engineering geological condition at the reservoir site was well elucidated; consequently the construction of the Ban Mong reservoir is approved and was expected to stat at the end of May 2010. |
