公路工程施工中软土地基应根据软土的物理力学性质,埋层深度,路基高度,材料条件,公路等级等因素主要采用换填法、表层处理法、抛石挤淤法、超载预压法、竖向排水法五种方法进行软基处理。介绍了这五种方法的设计思想和注意事项。 The soft ground in highway engineering construction should be based on the physical and mechanical properties of soft soil, depth of buried layer, embankment height, material conditions, road grade and other factors mainly using the exchange method, the surface treatment method, riprap method, overload preload method , Vertical drainage method five methods for soft-base treatment. The design ideas and precautions of these five methods are introduced.
