预应力管桩技术的单桩强度较高,能够有效提高路基的承载能力,减少了公路工程投入运营之后出现的不均匀沉降现象。对预应力管桩技术在公路工程施工中的应用进行了分析,并探寻加强质量控制的有效措施。 Prestressed pipe pile technology higher single pile strength, can effectively improve the bearing capacity of subgrade and reduce the uneven settlement after the highway project put into operation. The application of prestressed pipe pile technology in highway construction is analyzed, and the effective measures to strengthen quality control are explored.
