Effective Shoring Design with PLAXIS: Meeting Key Serviceability Criteria for Excavation Problems

Ground movement control is a serious subject and key to preventing failure due to loss of serviceability in geotechnical work. For underground excavations, the amount of ground movement is largely dependent on the shoring scheme and excavation sequence adopted. 

In the first instalment, these concepts will be demonstrated by reviewing a multilevel propped excavation design in PLAXIS.

You will learn:

• How to incorporate different support schemes (e.g. struts/tie-backs) in the design modeling workflow.
• The impact of key design choices, including prop locations/preloading and wall stiffness (rigid vs. flexible).
• How to perform checks against serviceability criteria (e.g. maximum allowable wall deflection limit).
