摘要
该文结合工程实例,对12m长钢筋混凝土(25cm×25cm断面)打入桩在施工过程中出现断桩和难打等问题进行分析,并通过验算,提出采用先打洞、再插桩的办法,解决桩基施打中由于桩基自身强度不足产生断桩的问题,同时对短桩设计提出看法。
Combined with the engineering case,the article analyzes the problems of broken pile and difficult driving in the curse of driving 12-m long steel reinforced concrete pile(25cm×25cm section),puts forward the method of firstly holing and then driving pile after checking computation to solve the problem of the broken pile in the pile foundation construction because of shortage in its strength of pile foundation,and at the same time puts forward the opinions for the design of short pile.
