为了尽可能准确地计算易塌陷土地基桩基础的负摩擦力,通过对易塌陷土地基桩基础负摩擦力成因的分析,计算出谦比希铜矿充填搅拌站桩基础负摩擦力和桩的极限承受力。与按国内计算湿陷性黄土地基桩极限承受力的方法所得的结果进行比较,桩的极限承受力提高了20%以上。工程费用明显节省。建成使用以来,基础沉降也完全符合设计要求。
In order to calculate the negative friction force of pile foundation in collapsible land as accurately as possible, the negative friction and piles of pile foundation of Chambishi copper mine filling station are calculated by analyzing the cause of negative friction of pile foundation in collapsible foundation. Ultimate bearing capacity. Compared with the results obtained by the method of calculating the ultimate bearing capacity of collapsible loess foundation in China, the ultimate bearing capacity of the pile is increased by more than 20%. Significant savings in construction costs. Built and used since the foundation settlement also fully meet the design requirements.
