摘　　要：详细分析了静载荷试验桩顶沉降的影响因素,对无明显陡降段试桩曲线成果分析方法进行了深入探讨,指出可采用判据计算值所对应的桩顶荷载作为桩的极限承载力近似值,并给出了判据量化表达式。This paper analyzes the factors affecting the settlement of test pile top under static load, and probes into the analyzing methods for the results of test-pile curve concerning the part without obvious drop-down, based on which, it is pointed out that the load on pile top which corresponds to calculated data of criterion could be used as the ultimate bearing capacity of pile. Meanwhile, a formula of criterion is given.
