Each step, from initial setup to advanced modeling techniques, is explained in detail. In this lesson, the process of jet grouting, a ground improvement technique, is explored. Jet grouting involves the injection of a cementitious grout into the soil at high pressure to create columns or panels that enhance the soil's properties. This method is commonly used for stabilizing soft soils and increasing their load-bearing capacity.

The implementation of vertical drains within a 3D model is demonstrated, allowing for the analysis of their impact on reducing settlement time. Factors such as drain spacing, length, and their interaction with preloading are analyzed to optimize consolidation. By the end of the lesson, an understanding of how to effectively combine preloading and vertical drains in PLAXIS 3D is achieved.

Jacking pit design: As a Geotechnical Engineer, I found the design of a jacking pit particularly intriguing. I utilized Geo-Studio 2018 for a 2D simulation of a jacking pit in granular soil, which was 8 meters deep. The analysis revealed a maximum capacity of 110 tons/m of the pit. Hence, to handle the Fj (permissible jacking force)=500ton the required minimum pit width was 4.6m. The design criteria aimed for a maximum horizontal soil movement of 1 inches. #soil #passive #2D #simulation #Jacking #pitt
