随着施工技术不断地进步,桩基础越来越多地用于建筑工程:桥梁、结构、房建等各方面,大有取笨重的扩大基础而代之之势。由于它是利用桩体与土基之间摩擦力来承担上部荷载,具有占据空间小、能避免大面积土方开挖、受天气条件影响小科冬季施工、能减少施工对周边环境的影响、施工作业面小、工期短等优点,实践已经证明它的这些优点尤其明显。
With the continuous improvement of construction technology, pile foundations are increasingly being used in construction projects: bridges, structures, housing construction and other aspects, with a great deal of cumbersome expansion of the foundation and the potential. Because it is the use of friction between the pile body and the foundation to bear the upper load, with a small footprint, to avoid large areas of earth excavation, affected by the weather conditions small section of winter construction, can reduce the impact of construction on the surrounding environment, construction Small working hours, short duration and other advantages, practice has proved that these advantages are particularly evident.
