17- Excavation in sand

This tutorial describes the construction of an excavation pit in soft clay and sand layers. The pit is a relatively small excavation of 12 by 20 m, excavated to a depth of 6.5 m below the surface. Struts, walings and ground anchors are used to prevent the pit from collapsing. After the full excavation, an additional surface load is added on one side of the pit. Objectives • Using the Hardening Soil model • Modelling of ground anchors • Using interface features • Defining over-consolidation ratio (OCR) • Prestressing a ground anchor • Changing water conditions • Selection of stress points to generate stress/strain curves • Viewing plastic points Geometry The proposed geometry for this exercise is 80 m wide and 50 m long. The excavation pit is placed in the center of the geometry. #excavator #diaphragm #diaphragmwall #اكسبلور #explore #geotechnical #civilengineering #civil #plaxis #earthquake #تعلم #الهندسة_المدنية #autocad #slope #geotechnicalengineering #geotechnical_engineering #soil_mechanics #soilmechanics #stability #finiteelementanalysis
