摘要
结合工程实例,从成桩施工工艺、施工技术参数与截桩工艺等方面分析了CFG桩施工时断桩的原因,提出了接桩法、注浆法和2种断桩处理措施。
Combined with the engineering example,analysis is made on the reasons for pile breaking in CFG pile construction technology,technical parameters and cutting pile technology.And the broken pile treatment measures by pile extension and grouting are proposed.
