| 摘 要： | 钢管纤维桩工法是建筑物基础托换技术中较为先进和实用的工法。目前在国内托换工程实践领域应用还比较少，现行的相关规范尚未专门涉及。钢管纤维桩工法具有施工快捷，质量可靠，对基础土层及周围建筑物扰动小的特点，特别适合既有建筑物的基础托换工程（特别是旧城改造和古建筑物地基加固工程），是一种值得推荐的建筑物基础托换技术。文中全面介绍了这种工法的特点、设计以及施工环节，并结合成功的实例，展示了该工法的实际工程应用效果。

| Abstract: | The characteristics, designing, construction and checking methods of the advanced and applied underpinning technology, steel fiber pile technology, are introduced. In fact, the technology is rarely discussed or described in domestic works and even in the codes nowadays. But it’s really an excellent technology for underpinning construction of existing buildings for its rapid construction and reliable quality, especially for rebuilding of old cities and reinforcement of ancient buildings. The effect of the underpinning technology is also showed with some successful underpinning projects as well. |
