  • Multilevel Excavation and Dewatering using "Well" feature

    Hi. I have a multilevel excavation problem for which I want to use "create well" feature to pump out water before every level of excavation. Initial groundwater level is at 2 m below ground surface. The excavation is in 4 stages and final excavated level…

  • Plastic point generated around the plate element

    Greeting to everyone, I performed excavation in Plaxis 3D using plate elements as retaining walls. When I check the plastic point at a certain volume element (in front of the plate element), the plastic point is also generated around the plate element…

  • Reasons for pairing Plastic and Consolidation analyses with each excavation phase?

    Hi all, I've inherited a model from a consultant of a staged excavation in saturated, stiff clay that is expected to behave undrained. Once the excavation goes below water table, each stage was given a Plastic calculation (0 days) and a Consolidation…

  • Stability Analysis of Deep Excavation

    Greetings, I conducted stability analysis of deep excavation at the final stage using Plaxis 2D analysis. The excavation depth is 15 m while the penetration depth is 12 m. When performing stability analysis, the plate element (diaphragm wall) has a large…

  • Instrumentation monitoring plan during excavation in soil etc.

    Hi all, If anyone know how to decide the spacing between the instrumentations which are needed to provide on site to measure in-situ data like ground settlement markers, prism markers, water stand pipe, piezometers, inclinometers etc. Thanks.

  • How can I assign properties of Anchor Rod and Steel Sections (H-beam/C-channel) for along a cantilever sheet pile wall in PLAXIS 2D?

    I used anchor to define 12mm tie rods at 3m and 6m depth along the sheet pile. For calculating EA, I considered E = 2E8 KN/m2 and A = 0.000113 m2. Therefore EA = 22600 KN/m3. Is it the right approach top assign tie road also I am getting more displacement…

  • Influence zone in deep excavation

    Hi all, Anyone, please tell how to estimate the influence zone during the deep excavation (this helps to check whether the surrounding buildings affect or not and then can do impact assessment). I got these details from one paper. Thanks.
