Title: Preloading as a Technique for Ground Improvement Auto-description: In this video, the professor of construction engineering explains the soft ground improvement technique known as preloading. This technique involves applying a load to the ground equal to or greater than the load the final structure will support, which causes the soil to consolidate, increasing its strength and reducing post-construction settlement. It focuses on cohesive soils, which, under small overloads, experience significant settlement and have low shear strength. Preloading is effective up to tens of meters deep, and it is important to have a "load memory" in the soil, thus achieving lower settlements during future recharges. This technique is applied to natural and artificial soils, although it has limitations in overconsolidated soils. Preloading is common in port projects, and its typical application involves piling fill on the ground, which, after consolidating, is removed for new construction. The advantages of preloading include its low cost and the use of simple, inexpensive equipment, allowing for direct assessments and reducing the risk of soil liquefaction in seismic zones. However, the technique requires time for consolidation and can affect structures close to the ground. Consolidation can be accelerated through drainage-enhancing treatments, such as vertical inclusions or vertical drains, achieving rapid consolidation with minimal post-construction settlement. Finally, the video mentions that the Ministry establishes parameters for preloading, including settlement monitoring during and after construction and safety measures. The professor's personal blog is recommended for more information, and he encourages you to subscribe to his YouTube channel to continue learning about construction techniques.
