目前各级公路尤其是高等级公路路基在施工过程中对地质情况勘探不详细,软土地基处理不到位,施工工艺、路基填筑材料等原因造成通车后路基出现沉降,路面出现规则性的纵、横向裂缝,影响行车安全,如何快速处理路基的沉陷,对路基进行加固,同时尽可能的减少施工影响,采用注浆固结法进行处理,可以快速有效的提高土体的强度,减少土体的中的含水量,提高应力,保持路基的整体稳定性,减少路基的沉陷开裂,提高公路服务水平。
At present, the highway at all levels, especially high-grade highway subgrade in the construction process of exploration for geological conditions is not detailed, soft foundation treatment is not in place, construction technology, roadbed filling materials and other reasons caused by subsidence after the opening of the road, the road appears regular vertical , Transverse cracks, affecting traffic safety, how to quickly deal with subsidence subgrade, the subgrade reinforcement, while minimizing the construction impact, the use of grouting consolidation method for processing, can quickly and effectively improve soil strength, reduce soil Of the water content, increase the stress, to maintain the overall stability of the roadbed to reduce subsidence cracking subgrade to improve the level of highway services.
