Excavation with no drop down in water level
Dear Sir,
I have an excavation model in Plaxis 2D with SBP wall at both sides. We have proposed recharge well on site to prevent the water level drop down. Therefore, In Plaxis model, I defined the pore water calculation type as "phreatic line" with…
Plaxis 3D_How to model post-tension concrete slab that acts as permanent support for retention system?
Hi All,
I am working on the analysis job for an excavation work?
So far I have proceeded to the completion of excavation that has been temporarily supported by struts?
I am about to activate the ground floor level slab and deactivate the struts…
Wall deflection decrease after further excavation
Hi everyone, I am working on a simple excavation and lateral support problem with soil berm as support for intermediate stages before reaching the final excavation level. For the last stage of soil berm removal before reaching the final excavation level…

Dynamic analysis
Hi there,
I am in the process of conducting a dynamic analysis on a deep excavation (>28m). The water table is close to the surface and the excavation wall consists of secant wall and anchors. Therefore, I am running a coupled flow analysis during…

Modelling Bored Pile Wall in Plaxis 2D Ultimate
Hi,
I need to model a bored pile wall with shotcrete between the piles and a pile head cap in Plaxis 2D ultimate. Am I better to model this as an equivalent plate element using the effective stiffness per meter length or as an embedded beam row?
Thank…

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…
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…
In dewatered excavation with high water table, why do I see external water loads on excavation side? How to prevent external water loads?
I have a dewatered tied-back caisson wall excavation with a high water table in PLAXIS 2D. Throughout excavation stages I set soil clusters to dry. ymin boundary is open, all others are closed. Why are external water loads showing up in output? How to…
