摘要
该文对实际工程中三岔挤扩灌注桩(简称DX桩)与直孔桩的抗压试验数据进行了分析。分析表明由于三岔挤扩灌注桩有承力盘或承力岔,其受力呈现为摩擦端承桩受力模式,相比直孔桩具有承载能力大,沉降小的良好受力性能。
The article analyzes the pressure resistant test data of three-fork squeezing bored pile and column pile. The analysis shows that the stress of three-fork squeezing bored pile presents the friction end bearing pile stress mode because of its bearing tray or bearing fork. It has the greater carrying capacity and the better stress performance of small settlement than the column pile.
