摘要
既有线浅基桥梁成为影响桥梁承载能力和危及行车安全的隐患,分析了桥梁浅基产生的原因和构成的危害,介绍了治理浅基的一般办法,重点阐述了利用高压旋喷注浆法加固浅基桥墩技术,针对两座桥,设计了加固方案,进行了工程实施,并研究了加固效果。
The bridges supported on the shallow foundations of the existing railway lines become a hidden peril affecting the carrying capacity of the bridges and endangering the safety of the trains traveling on the lines. In this paper, the causes that the shallow foundations come into being and the harms that may come from the foundations are analyzed, and the general method for remedying the shallow foundations, particularly the high-pressure mortar churning and jetting technique of strengthening the shallow foundations, is described. By way of example of two bridges, the design of strengthening the foundations is conducted, the strengthening construction is implemented and the effect of the strengthening is studied.
