摘要
针对宁波地区软土地质条件的特点,结合镇海新区一典型城市道路主干路工程实践,探讨了对饱和、深厚软土地质条件的地基处理方法。通过对软基工程计算分析后,在道路一般路段采用路用性能好的填料进行路基填筑或换填。对于桥接坡路段地基采用真空—堆载联合预压排水固结法处理。该工程处理两年来,取得了良好的软土地基处理效果及经济效益。
Aiming at the characteristics of soft soil geology in Ningbo,a foundation treatment method to saturated and deep soft soils has been discussed with a typical case of urban main road project in Zhenhai New Area.Through a calculation analysis of the project,the normal section could use the filler with good service performance to make roadbed filling or exchange filling.And the foundation of the bridge-slope section should adopt the treatment method of vacuum-surcharge preloading and drainage consolidation.It has gained excellent soft soil foundation treatment effect and economic benefit over the past two years.
