【摘要】 通过对灌浆技术应用于处理桥头跳车工程实例的分析,详细阐述了桥头跳车的成因,着重介绍处理桥头跳车的灌浆技术的作用机理、设计以及较为完整的施工工艺等,指出了施工中应该注意的问题。工程实例结果表明,采用钻孔压力灌浆提高台背路堤的密实程度和整体强度、减小沉降量是一种简便易行、经济合理且行之有效的方法。更多还原

【Abstract】 Cause of bumping at bridge-head is expounded by analyzing the actual project of bumping treatment, in which the grouting technology is introduced.The mechanism,design and complete construction technique of grouting technology are heavily introduced,problems that should be paid attention to during construction are pointed out.The result indicates that the way to improve the density and whole strength, reduce the settlement by grouting with borehole pressure is easy to carry out,and is economic and effective.更多还原
