https://communities.bentley.com/products/geotech-analysis/f/forum/219674/water-pressure-in-the-gap-between-pile-and-soilHello, I have a doubt whether the Plaxis-3D could simulate the water pressure in the gap between pile and soil. The background of this is when cyclic load applied at the offshore monopile, the gap would appear at least on one side of pile, which woulden-USTelligent Community 12https://communities.bentley.com/thread/672639?ContentTypeID=1Mon, 20 Sep 2021 07:27:42 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ab6c7dc6-2e60-4935-a258-21da7cd20c5eBerk Demir<p>This is a very good question. Let&#39;s see what happens when a pile is loaded laterally. By going back and forward, it creates a gap between soil and pile. Also, there is a wedge failure possibility. So, any soil at the top near the pile is really disturbed.</p> <p>What can we see in Plaxis? Plastic points near the pile can be seen easily which simulates the wedge shaped failure.&nbsp;</p> <p>Filling of the gap with water is documented in the papers, but it does not add any additional load to the pile, does it? We already have water defined in the model that exerts pressure, after you have&nbsp; a gap between soil and pile, you can see the ground water, that&#39;s all. So there is nothing to model there.</p> <p>The more important part, which is also treated with compression only p-y curves in the analytical approach, is -as you said- gap closure. That will affect the results significantly.</p><div style="clear:both;"></div>
