Hello
I wonder if anyone can provide an equivalent or similar ISO for the following ASTM standards
ASTM D854 specific gravity test of soils
ASTM D7012 – unconfined compressive test of rocks
ASTM G57 – resistivity test of soil for grounding (Wenner method)
ASTM G162 – soil corrosivity...
This may be a simple solution.
Assume no moisture - rockfill materials. When rockfill is placed in a truck for weighing (assume loose), the unit weight would be unique, based on (a) gradation, (b) particle shapes, and (c) Specific gravity of rocks. For (a), the well graded the rockfill, the...
Is there a sophisticated software available in the market which can handle management flows for construction materials (such as granular and impervious fills) for a large dam project? The software should be able to provide supplies and demand from various deposit/ borrow sources, time flows...
For a large project, such as a hydroelectric development, the construction drawing will contain a project layout and control drawings, in which dimensions will be provided in true lengths, rather than in a UTM coordinates, such as NAD 83 coordinate system.
Since the topo maps are established...
Could someone remind me on the basic guide on how to assign stations numbering for roadways, dykelines, etc?
Any difference between metric and imperial system ?
Example:
A dykeline 15 km long:
Start from 0+00 and end at 15+00
or
Start from 0+000 and end at 15+000
A road 20 miles long:
How...
What size of anchor block is required for mooring a 4000 tonnes barge (gross weight) on a jetty? Is there a rule of thumb to use, i.e how big is the concrete block and how many?
Who are the prominent experts in the field of hydrogeologist? I am thinking about an expert with practical experience, but understand about the hydrogeological modeling in the context of a major dam construction. Concerns related to karstic limestone bedrock as well as potential overburden...
Most of the hydroelectrical projects, especially those with high output power utilizing large size turbines in their powerhouses, the powerhouse is usually founded on sound bedrock. This will eliminate long term foundation settlement, potential instabillity due to earthquake, liquefactions, etc...

To obtain stresses and strains in a dam foundation, as a dam is being constructed and the water is impounded afterwards, what is the most appropriate software available in the market today to carry out such a modeling analysis?
Is FLAC the software of choice for solving geomechanics problems...
I wonder if there is a table which provide some information about Modulus Subgrade Reaction (ks) for various type and quality of rocks. In particular, I am looing for ks value for a dolomitic limestone bedrock.
Is there any relationshipp between ks and Young's modulus of the rock, or between...
I am wondering who do you think are prominent expertise in geotechnics in the following area
Soil mechanics - Morgenstern, Meyerhoff, Ralph Peck
Permafrost foundations
Foundations on soft soils - R.D Holtz
Liquefaction and seismic - Ambroesays
Geosynthetics - Giroud
marine clay/soft clay...

How to determine Ca (calcite) and Mg (dolomite) components of Limestone rock accurately ?
There is an XRD (X ray diffraction) method which is used , based on calibration curve suggested by Tennant and Berger (1957 paper). There is also aother method based on Rietveld refinement of XRD patterns...

A shear key construction requires crushed rock materials, with maximum sizes between 6 and 8 in. What typical gradation should be selected to get the maximum density without compaction effort. The crushed rock will be dumped by the excavator bucket (no compaction), after a 3m wide shear key...
A shear key construction requires a crushed rock materials, with maximum sizes between 6 and 8 in. What typical gradation should be selected to get the best density without compaction effort. The crushed rock will be dumped by the excavator bucket, after a 3m wide shear key trench (up to 6m...
When I was working in Riyadh, SA, it was very common to probe the foundation Limestone for large structures, particularly if it is a sensitive and huge structure. The area was notorious for having large cavities in the limestone bedrock formation. Why is it a big fuss to probe under the...
How much access do you get for research paper in geotechnical field ?
I did some research work a while back and the following papers from Can geotech journal maybe helpful.
Also , an excellent book

For an earth core dam with outer granular shell layers, the designed for the core of the dam is usually based on economic and availability of the fill materials. If the impervious fill material (clay) is readily available and cheaper than granular fills, the dam can be designed with relatively...
