摘要
文章以苏州地铁4号线和2号线部分区站勘察资料为例,将勘察报告中常用的静力触探经验公式计算出的地基承载力特征值与载荷试验结果对比,分析土层在不同状态下最接近载荷试验结果的经验公式,阐述如何在较多的经验公式中选出更接近实际地基土承载力的计算公式,总结出适用于苏州地区各不同土层静力触探经验式的合理性,为苏州地基土承载力计算公式的选用提供参考。
This paper takes the survey data of some district stations of Suzhou Metro Line 4 and Line 2 as an example, compares the characteristic value of the foundation bearing capacity calculated by the static cone penetration empirical formula commonly used in the survey report with the load test results, and analyzes the soil layers in different states Below is the empirical formula that is closest to the results of the load test, and explains how to select a calculation formula that is closer to the actual foundation soil bearing capacity from more empirical formulas, and summarizes the reasonable empirical formulas applicable to different soil layers in the Suzhou area. It provides a reference for the selection of the calculation formula for the bearing capacity of Suzhou foundation soil.
