桩顶到底需要多大的压力才能打入设计标高，才能使单桩达到最大承载力，这是工程中最实际和最有价值的问题。通过静载试验，得到了桩顶终压与单桩极限承载力关系的真实的工程实践。通过钢弦杆应力计在预应力管桩中的应用，论述了通过测量应力计的频率来确定极限轴阻力标准值和极限端承标准值的过程和原理。
How much pressure need before piling into the design elevation and getting the largest bearing capacity of single pile,it is the most practical and valuable question in engineering.The real engineering practice for the relation of final pile pressure and ultimate bearing capacity of single pile is obtained through the static piling and load test.According to the application of steel chord stress meter to prestressed tubular pile,the process and principle of limit shaft resistance standard value and limit end bearing standard value are discussed by measuring the frequency of the stress meter.
