We are adopting the Hardening Soil Model with Small Strain Soil Model and are a bit confused on the value of power m to adopt for are soil due to varied understanding of the use of this parameter.</p> <p>&nbsp;</p> <p>Understanding 1: this parameter is used to represent the increasing stiffness Eur with depth and cam be adjusted to mimic the actual variation in stiffness parameter with depth. Where there is no variation with depth a very small value of 0.001 can be adopted. True or false</p> <p>Understanding 2: Adopt a value between 0.5 and 1 (or default value 0.5) to inform the variation in unload reload stiffness values based on the stress variation. This does not have anything to do with stiffness variation with depth but all to do with the stiffness values to be adopted at different stress levels. If so how do we model the variation in stiffness with depth.</p><div style="clear:both;"></div>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Thu, 22 Apr 2021 00:33:13 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ca1521d4-bbed-4bc6-875c-afd8bf5fc891Ask a question in a forum.
