Geotech study for hydropower plant
Geotech study for hydropower plant
(OP)
Hi everyone,I would appreciate if any one of you could give me some insight into it:
1. What should be the depth of bore-hole for drilling for geo-technical study of hydro-power plant??
2. What are the type of lab and in-situ test required to be conducted as a part of geo-technical study??
3. how is electrical resitivity related to seismic refraction study??
Please, do throw some light on it.

RE: Geotech study for hydropower plant
The depth and number of borings will depend on the foundation size and loading. Further, it depends on the local soil conditions, which most of us are not going to know.
The lab tests will depend on the types of soils encountered. They could include triaxial shear, direct shear, consolidation, classification indices, unconfined compressive strength....and many others.
I have no experience with seismic refraction.

I used to work on large scale dam projects. You need to provide better insight on what you're doing to further this discussion.
Are you building a dam (you only talk about the power plant)?
Is it an earth dam, RCC dam, concrete arch dam, ogee dam, gravity dam.
Both resistivity and refraction are geophysical tools, so their related.
More information needed to help.

Thanks guys for the insight. Further help is most welcome. :)

You'll need strength data on the rock mass.
You may need stress-strain data for the rock mass.
You'll need packer-test data on the rock mass (this is done in the borehole.
You may need an aggregate study if you are using local aggregates to batch your concrete.
You may need low-strain shear modulus (seismic?) if there is a seismic component to the project.
Here's my thesis: http://home.comcast.net/~fatt-dad/thesis.pdf
Just a few items that come to mind.

Hire a geotech and let them do their job

CVG, indeed we are hiring geological expert for the studies. And we have civil engineers friends from our project involved in it. We were just discussing about it and thought it won't hurt to have some more clarification. Thanks for the insight!
msucog, yeah the studies looks very complicated and sophisticated. Thanks for the information!
