摘要
本文结合膨胀灌注桩静载试验,探讨膨胀灌注桩增载机理,给出便于工程设计的增载计算公式,计算结果与实测吻合较好。
Combined with Static loading test of cast -in -place pile with expansion agent, the increase loading mechanism was discussed in this paper. Calculating formula for increased loading of engineering design is also presented, and the calculated results agree well with onsite test date.
