在关于大跨径桥梁的很多报告中,介绍桥梁基础的仅占少数。显然,桥梁工程师们从事上部构造的工作大大超过了下部构造。从而导致了上部工程比基础工程在技术上发展较快,在经济上也比较省。因此;国际桥梁与结构工程协会(IVBH)决定,近年中要更多地重视基础工程。毫无疑问,已积累的基础工程知识和经验,对今后修建更简化和经济的基础工程会作出贡献的。为此, In many of the reports on long span bridges, only a few account of the foundation of the bridge. Obviously, bridge engineers work in the superstructure much more than the substructure. As a result, the upper part of the project is technically faster than the basic one and economically more economical. Therefore, the International Association of Bridge and Structural Engineering (IVBH) has decided that more emphasis should be placed on basic engineering in recent years. There is no doubt that the accumulated basic engineering knowledge and experience will contribute to the future construction of a more streamlined and economical foundation project. to this end,
