摘要
结合某逆作法施工工程实际情况,针对大直径扩底灌注桩设计中遇到的几个问题进行了分析,着重介绍了钢管桩安装技术及桩基设计要点,并通过桩基沉降监测得出采用大直径扩底灌注桩结合桩端后注浆能提高桩基承载力,降低桩基沉降。
Combining with certain engineering condition with reverse construction method,this article analyzes several problems occurring in the design of enlarged grouting pile with large diameter,mainly introduces steel pipe column installation technology and pile foundation design points.Through pile foundation settlement survey,it achieves that： it can improve pile foundation bearing and reduce pile foundation settlement with enlarged and large diameter grouting pile combining post grouting at entrance pile.
