第四系土层大直径超长桩的承载特性

The Bearing load Characteristic of large diameter and Super-Long pile (Bored Pile) in Quaternary soil

在没有良好的持力层 (基岩或砂、卵石层 )和成熟经验可借鉴的情况下 ,对第四系土层大直径超长桩 (钻孔灌注桩 )的承载特性进行了分析。并以分析结果为依据 ,预估单桩承载力 ,结果与静力试桩结论相吻合。

The bearing characteristic of large diameter and super-long pile in quaternary soil layer is analyzed in the case of no good bearing layer (such as rock, sand and cobble layer) and no ripe experience. Based on the analytical results. The allowable pile bearing load is prestimated, And The outcome is in conformity to static pile test.
