【摘要】 采用静载试验及数值计算相结合的方法,分析混凝土灌注螺纹桩桩周土体应力分布情况、螺齿宽度、螺距等桩型参数对螺纹桩承载性能的影响,得出对螺纹桩承载性能的影响规律,以优化桩型设计参数。通过对工程造价的比较,表明螺纹桩与直桩在相同承载力下,造价大大降低。更多还原

【Abstract】 Using the combination of static load test and numerical calculation,the effects of pile parameters such as the stress distribution of soil surrounding a pile,helical width and helical pitch etc on the bearing behavior of a bored screw pile were analyzed,whose influencing laws were obtained,thus optimizing the design parameters of this sort of pile.Through a comparison of project cost,the cost of a screw pile is much lower than that of normal one under same bearing capacity.更多还原
