In the future development will make up for their shortcomings to strengthen their advantages, based on the study of new construction technology also possible development direction.Key Words: Pile foundation Bored pile New technology Concrete1 引言桩基是一种古老的基础型式。桩工技术经历了几千年的进展过程。无论是桩基材料和桩类型,或者是桩工机械和施工方法都有了巨大的进展,已经形成了现代化基础工程体系。在某些情况下,采纳桩基可以大量减少施工现场工作量和材料的消耗。70 年代,中国曾发生了几次大地震。以其中的唐山大地震为例,凡采纳桩基的建筑物一般受害轻微。这说明桩基在地震力作用下的变形小,稳定性好,是解决地震区软弱地基和地震液化地基抗震问题的一种有效措施。如今桩基础施工工艺种类繁多,各类新型施工工艺层出不绝,本文主要介绍桩基础新型施工工艺并浅谈桩基础的未来进展方向。2 桩基础施工新技术2.1 静力压桩2.1.1 静力压桩的含义和适用范围用静力压桩机或锚杆将预制钢...
