砂泥岩地层基桩自平衡法应用研究

Study on Application of Self-balanced Method in Foundation Pile in Sand Shale Stratum

该文以重庆地区某砂泥岩地层基桩为研究对象,采用自平衡静载试验测量计算了该基桩的承载力与侧阻力,并选取该拟建设施的3根基桩,评估了砂泥岩地层条件下的基桩承载特性及自平衡静载试验效果。结果表明,使用自平衡静载试验能够较准确地评估砂泥岩地层条件下的基桩承载能力,可为西南地区砂泥岩地层下基桩承载能力计算提供参考。

Based on the selected foundation piles in sand shale stratum in Chongqing, this paper calculated the bearing capacity and side resistance of the pile using self-balanced static load test. Three foundation piles of the to-be-built facility were selected to evaluate the bearing characteristics and the effects of the self-balanced static load test of the foundation piles under the condition of sand shale stratum. The results showed that the self-balanced static load test can accurately evaluate the bearing capacity of foundation piles in sand shale stratum, which can provide references for the calculation of the bearing capacity of foundation piles in sand shale stratum in the Southwest of China.
