Course content

2 sections • 12 lectures • 2h 16m total length

Input data1:33
Set the adopted soil stratigraphy and shoring geometry for the plexus model, with CH 7750 steel piles and 51 m anchors; outline construction stages including surcharge, excavation, ground anchors, dewatering.
Building a Plaxis model - Part 17:40
Build a Plaxis 2D model with hardening soil model, set boundaries, input e50 ref and r inter 0.33, establish borehole groundwater level, dry two clay layers, and define shoring geometry.
Building a Plaxis model - Part 28:55
Build a plaxis 2d model of a shoring wall with plate elements for steel sheets and pile wall, depth 12 m reduced by 0.2 m, and interfaces for soil-structure interaction.
Material parameters of structural elements9:54
Define material data sets for plate, anchor, and embedded beam elements in a steel sheet pile wall, calculating axial and bending stiffness from Young's modulus and Poisson's ratio 0.3.
Generation of finite element mesh3:22
Generate the finite element mesh from the mesh tab, choose the element size, and locally refine at cluster areas, lines, and points near the shoring wall.
Assigning construction stages7:00
Define construction stages in Plaxis 2D by adding calculation phases to activate the shoring wall loads, ground anchors, soil clusters, and groundwater conditions; run and save the staged analysis.
Results of analysis and updating parameters of the model19:13
Analyze results from the Plaxis 2D retaining wall study, update model parameters, and assess lateral deflection, internal actions, and anchor loads across construction phases. Verify stability with a safety factor.

Input data2:26
Analyze the input data for a three-level basement modeled in Plaxis 2D, covering soil stratigraphy, geometry, and two-row lateral support with ground anchors and props.
Building a Plaxis model12:56
Build a Plaxis 2D model by adapting an example, editing lines, and setting excavation and shoring parameters, then update soil layers and apply a long-term load on the diaphragm wall.
Material parameters of structural elements12:18
Define and assign material parameters for diaphragm walls, plate elements, anchors, and slabs in plaxis 2d, including unit weight, axial and bending stiffness, and short- and long-term reduction factors.
Generation of finite element mesh and assigning construction stages32:21
Generate a finite element mesh and define construction stages for a diaphragm wall project in Plaxis 2D, including groundwater conditions, phase management, and stability checks.
Results of analysis18:50
Open the output program to check results, inspect lateral deflections and bending moments of the shoring and diaphragm walls across phases, and export plots and data to Excel for analysis.
