Hello colleagues,
We are currently working on a project that involves determining the gradation of 24"-minus rockfill. We've been searching for standard procedures, such as those provided by ASTM, but unfortunately, we haven't found any suitable ones yet. If any of you are aware of any...
Good morning
We have a 20 m high retaining wall with a 4x4 m footing seating right beside the edge of the retaining wall. How can I estimate an equivalent lateral force (and its location) on the wall caused by the footing? I've been thinking of two approaches so far but I am not sure if are...
Hello all,
I have a question (and maybe not the smartest one in the world) that got me confused.
Let’s say there is a normally consolidated clay layer overlain by sand and gravel deposit. There is a dam constructed on top of the sand and gravel deposit. Dam weight introduces excessive pore...
I am looking for information on earth dams/cofferdams built by dumping in the water. The question of interest is what slope would the material under water be if dumped from a barge or by end-dumping from trucks. The material could be rock fill, low plasticity clayey silt (50-60% fines) and sand...
Hello again,
I am looking for a good summary on origins of FOS for short and long term slope stability. What is the main reason for the "short-term" FOS to be lower than the "long-term" one?
Thank you in advance,
CEMAB
Hello,
I would appreciate if you could share your experience on processing CPT data for the slope stability purposes. To be more specific, I have a record of interpreted undrained shear strength obtained from CPT. The Su values fluctuate substantially with the depth (see the attached file). I...
Hello,
I have a question regarding use of undrained shear strength of fine-grained materials for the long term stability assessment. I have found a few sources that provide a clear guideline on using drained strengths and pore water pressures corresponding to steady seepage conditions for...
