在9米半径离心机上测试的分层土壤模型中，土壤夹层对测得的锥贯入阻力的影响进行了研究。土壤剖面由上覆和下覆低塑性粘土质粉土层之间的一层砂组成。砂层厚度沿着模型长度从0到240 mm（模型比例）不等。模型一侧的砂是相对密度为44%的松散砂，另一侧的砂是相对密度为88%的密实砂。粘性粉土的塑性指数（PI）为6，超固结比（OCR）约为1.5。使用直径为4 mm、6 mm和10 mm的锥形贯入仪沿模型的宽度和长度沿着进行了多次锥形贯入探测。描述了模型的建造过程、数据处理和锥形贯入试验结果。
The effect of soil interlayering on the measured cone penetration resistance was examined in a layered soil model tested on a 9-m radius centrifuge. The soil profile consisted of a layer of sand between overlying and underlying layers of low plasticity clayey silt. The sand layer thickness varied from 0 to 240 mm (model scale) along the length of the model. The sand was loose with a relative density of 44% on one side of the model, and dense with a relative density of 88% on the other side. The clayey silt had a plasticity index (PI) of 6 and over-consolidation ratio (OCR) of about 1.5. Multiple cone penetration soundings were performed along the width and length of the model using cone penetrometers with diameters of 4, 6, and 10 mm. The model construction procedure, data processing, and cone penetration testing results are described.
