Plastic calculation vs Consolidation calculation

원호 정 — Thu, 02 Jun 2022 09:47:13 GMT

Hi,

I have a question regarding consolidation calculation. As you can see, the tutorial on “Construction of a road embankment” (p72) noted that this analysis applied the consolidation analysis (p79). I think the total consolidation settlement includes the elastic settlement, primary settlement, and secondary settlement.

Does consolidation calculation way consider the Plastic calculation for the elastic settlement? If this is a fact, the elastic effect calculates automatically in analysis, right?
What exactly is the difference between Plastic calculation and Consolidation?

Please answer me.

Best regards

water/ocean current in Plaxis

원호 정 — Thu, 14 Apr 2022 08:17:14 GMT

I am checking the stability of slope due to dredging activity. I want to introduce water/ocean current (water flow rate) of water above the sea floor, in my model. Can we model such effects in Plaxis?

Plaxis: Site response facility

원호 정 — Wed, 08 Sep 2021 09:06:34 GMT

I have a query about Plaxis 2D (v.21 Ultimate) Site Response function that can be used for 1D Site Response Analysis (SRA). When we select “Site Response” from the “Modify soil layers” menu, Plaxis automatically converts the main geometry of the model into 1D geometry and the meshing is also done with 6-noded elements.

I would like to know, whether such meshing is OK for the Site Response Analysis, OR I have to modify the mesh size as suggested in Plaxis 2D (2015) Ground Response Analysis report, i.e., the suggestion of Kuhlmeyer & Lysmer (1973).

Secondly, I would like to know whether the following conditions are OK while selecting dynamic loading.
The Static Line displacement (U_x,start,ref) in the Dynamic module should be,
1) U_x,start,ref = 0.5 m ; In case of Rock outcrop motion ?
2) U_x,start,ref = 1.0 m ; In case of Bedrock (underlying of soil layer) motion ?
