| 摘要： | Basal reinforcement over soft soils has been used for several years as a practical and economical alternative to traditional ground improvement techniques. One or multiple layers of geosynthetic reinforcement can be installed directly between the embankment fill and the soft foundation soils to increase the design safety factor and span between piles, as well as to bridge sinkholes (Figure 8). Design methods are available internationally to properly identify the required tension and subsequently the design strain. To guarantee the required design life, installation of the geosynthetic reinforcement should be carefully carried out, preparing a flat surface clear of sharp objects, ensuring an accurate alignment of the rolls with proper overlap between the end of one roll and the beginning of the next one, and providing continuous bond length or edge anchoring. |
