Indian Valley Reservoir
Scope/Solutions
The Indian Valley Reservoir provides long-term irrigation storage and flood control. A 2010 inspection report recommended seismic analyses of the floodgates and control structure to confirm the gates could be raised following a earthquake. SGH evaluated the seismic performance of the two structures.
SGH assessed the expected performance of the structures in a maximum design earthquake when the reservoir water level is at its maximum level under normal operating conditions. Highlights of our work include the following:
- Developed finite element models of the reinforced concrete control structure and steel radial arm tainter gates
- Evaluated the control structure for uncracked and cracked conditions
- Analyzed the gates for both downstream and cross-steam loading
- Compared the anticipated demands to the structures’ capacities
- Concluded a maximum design earthquake should not cause deformations or damage that would prevent the gates from opening

West
Golden Gate Bridge North Anchorage Housing
The District determined the bridge could not reliably survive a repeat of the Great 1906 San Francisco earthquake and elected to undertake a multi-phase retrofit of the structure and foundations.

Bingham Canyon Mine
SGH evaluated the tunnel structure and helped the mine operator establish a monitoring program to identify when the tunnel exceeded its ability to support additional load.
