Geotechnical Data Tables

Soils Data

Laboratory Soils Testing – Laboratory tests were conducted on soil samples collected from borings on the dam during the 2009, and 2012 subsurface explorations. Soils from 08-EBD-65L through 08-EBD-70L and 08-EBD-74, 08-EBD-76, 08-EBD-78A, 08-EBD-80, E-24 through E- 26 (2009) and E-39 through E-57 (2012) were tested for Atterberg Limits, gradation, USCS name and symbol, and moisture content. The only soil samples that were collected and tested during the 2011 geotechnical investigation were from the six road borings (R-1 through R-6).

These soils were tested for Atterberg Limits, moisture content, grain size distribution, California Bearing Ratio (CBR) and USCS symbol. Standard Proctor (ASTM D 698) and shear strength was determined on samples 08-EBD-65L through 08-EBD-70L from the 2009 investigation.

Specific Gravity – Specific Gravity was determined for random samples from borings 08-EBD- 65L through 08-EBD-70L and 08-EBD-74, 08-EBD-76, 08-EBD-78A, 08-EBD-80, E-24 through E-26 form the 2009 subsurface exploration and borings E-40 to E-53 and E-57 from the 2012 geotechnical exploration.

Permeability Testing – Soil samples from borings 08-EBD-65L through 08-EBD-70L and E-24 to E-26 from the 2009 subsurface exploration were tested for permeability.

Compaction Testing – Compaction testing was accomplished as part of the 2008-2009 subsurface investigation program. The following chart shows the results of six Standard Proctor compaction tests (ASTM D 698) on sonic drilling samples. These samples were taken along the crest so samples contain either impervious core material or foundation soil. The sonic drilling process yields large composite samples. The exact method of test sample selection from the overall soil sample is uncertain so the amount of segregation during drilling or blending during sample preparation is uncertain.

Mineralogy of Soils – As part of the 2012 Geotechnical Data Report, 34 soil samples were collected from holes E-40 to E-53 and E-57 then tested for the amount and nature of clay minerals in the soil, paying particular attention to the occurrence of expansive clays. The full report, Mineralogy of Soils from the East Branch Dam: XRD Analysis of Silt- and Clay-size Particle Separations, is presented in this appendix.

Rock Data

Grouting Tables – Grouting programs were performed on both the right and left abutments in order to try to limit seepage through the rock. At the beginning of construction, in 1949-1950, the rock below the cutoff trench on the right abutment was grouted. Grout holes were drilled in two lines (A-line and B-line) from the concrete grout cap. For more discussion on the procedure, see section 3.1.1 of the report and the following tables in this appendix. Grouting on the left abutment occurred in 1955-1956. Eight nearly horizontal holes were drilled from the base of the spillway into the left abutment rock. The purpose was to reduce the seepage thought to be moving through a fractured sandstone layer, later identified as SS4. For more details see section

3.2 of the report and the following table in this appendix.

Laboratory Rock Tests – Laboratory testing was conducted on rock samples from the 2009, 2011, and 2012 subsurface and geotechnical explorations. Samples were taken from borings 08- EBD-72 through 08-EBD-74, 08-EBD-78 and 08-EBD-78Aduring the 2009 subsurface exploration, borings E-27 through E-38 during the 2011 geotechnical exploration, borings E-39 through E-47 and E-50 through E-59 from the 2012 geotechnical exploration, and E-60 from the 2012 geotechnical exploration/instrumentation installation. Each investigation tested for unconfined compressive strength (ASTM D 7012-10 method C), point load index (ASTM D 5731-08), and LA abrasion loss (ASTM C 131/ C35). Samples from the 2009 investigation were also tested for uniaxial compressive strength. Samples from the 2011 and 2012 explorations also tested for the peak compressive strength (ASTM D 7012 method D). In addition, samples from the 2012 exploration tested the Cerchar abrasivity (ASTM D 7625), seismic velocity and dynamic pulse (ASTM D 2845), splitting tensile strength (ASTM 3967), shear strength (ASTM D 5607), and paste pH.

Miscellaneous Data

Dye Testing Table – Dye testing was performed in several holes between 1955 and 1997. Select piezometers and weirs were monitored for dye. The following table summarizes the results of the dye testing, indicating location of injection and travel time.

2008 Geophysical Investigation – Investigation conducted in 2008 to identify, map, and model possible seepage flow paths through the right abutment of the dam.
