中文摘要：

针对高速公路施工过程中的异常情况，对加快堆载速度、增加超载高度、改善排水条件等质量改善措施进行了系统分析．借助灰色系统综合评价理论，建立了包括路段集、对策集和目标集的三维措施优选模型，用以确定不同影响因素下的最优处治措施．结合佛山“一环”软基处理过程中的实际情况，对不同路段进行了质量改善措施优选．通过对后期监测成果效果分析，验证了措施评价模型的可靠性．

英文摘要：

The measurements of increasing the loading velocity, increasing the surcharge height and changing the drainage path for the exceptional situation of the construction of expressway was analyzed. A 3D measures optimization model including section sets, countermeasure sets and target sets was established through the gray system technology. The model can be used to find the best treatment under different influence factors. The reliability of the model was evaluated through the analysis of the optimization measures and its effectiveness of different sections of the ground improvement project of the Foshan First Ring road.
