This paper focuses on the advanced modelling of soft Cameroon clays for the global prediction of the behaviour of geotechnical structures. A comprehensive set of experimental data on Cameroon subsoils from the oedometer and triaxial tests are analyzed in this paper in order to determine the stiffness and strength parameters for the Soft Soil model. It is based on 71 soil samples taken from both sides of the construction sites of several major structures across the territory. At the first approach, the soil samples taken were analyzed in a geotechnical laboratory to obtain physical and mechanical identification parameters specific to each soil type. The results obtained reveal that the analyzed soils are generally compressible clays. In the second phase, the law of behaviour of the Soft Soil model was used to characterize these Cameroon soils. Its parameters were obtained after calibration of the results of the laboratory tests obtained in first approach. The results obtained in this article can be compared to the different models obtained on clays soils around the world. The parameters are of the same order of magnitude as other clays modelled around the world.

喀麦隆粘土软土模型的刚度和强度参数评估

本文重点研究了喀麦隆软粘土的高级建模，以用于岩土结构行为的全球预测。为了确定软土模型的刚度和强度参数，本文分析了来自里程表和三轴试验的喀麦隆地基的综合实验数据。它是根据从全港数个主要建筑物的建筑工地两侧采集的71个土壤样本得出的。在第一种方法中，在岩土工程实验室对采集的土壤样品进行分析，以获得特定于每种土壤类型的物理和机械识别参数。获得的结果表明，所分析的土壤通常是可压缩的粘土。在第二阶段，使用软土模型的行为定律来表征这些喀麦隆土壤。在对第一种方法获得的实验室测试结果进行校准后，即可获得其参数。本文中获得的结果可以与世界各地在粘土上获得的不同模型进行比较。参数与世界上其他模型的粘土数量级相同。
