摘要
昆明地区由于特殊的地理环境,生成了具有广泛分布的重要的软弱土层。为了解昆明地区软土中的人工挖孔桩在上部荷载作用下,桩侧和桩端的受力机理及土层的变形机理,对此土层的人工挖孔桩进行了静荷载试验,对试验结果进行了分析研究,为今后的软土地基挖孔桩的设计和施工提供了有益的经验。
The region of Kunming because of special geography environment,born have the extensive the important and weak soil layer that distribute.According to the static loading test of artificial excavated pile in Kunming soft soil.Analysis the paper elaborated the experiment method of static load test and the pile load under the action of the determinate pile capacity.Its ultimate pile capacity is determine by displacement.The thickness of sediment is the major influence on friction of pile stem and resistance of pile toe.To experiment the result proceeded the analysis studies,for from now on of the soft soil foundation digs the design of the bore stake to provide the beneficial experience with construction.
