摘要
随着城市建设的不断发展,越来越多的建筑选址落在一些回填区和地层较复杂的区域,而且由于建筑高度的增加,基础选型也只能采用桩基,这样给桩基施工带来较多困难,无法用传统的工法完成施工。根据已有的工程经验,结合现场情况,对变截面超前扩孔全套管施工工法在漂石、填石地层中应用工法进行了分析总结,为其它类似项目的使用提供参考。
With the continuous development of urban construction,more and more building sites fall into some backfill areas and areas with more complex strata.Moreover,due to the increase in building height,the foundation selection would be limited to pile foundations.This could generate lots of problems during the construction of the fundation,which means it’s hardly to complete the implementation with traditional construction methods.In this paper,based on the existing engineering experience,together with the site conditions,the construction method of the variable cross-section advanced reaming full casing construction method is analyzed and summarized in the boulder and rockfill formation.The paper provides a reference for the use of other similar projects.
