| 摘 要： | 本文指出与安徽硬粘土的工程性质有关的地质成因,根据试验结果提出硬粘土的室内强度指标,并讨论这些指标所存在的问题,同时也讨论了在现场采用十字板(FVT)及标准贯入试验(SPT)测试强度的适用性,由于硬粘土的裂隙特性提出用现场的反算法确定硬粘土的抗剪强度,最后,给出一个滑坡实例说明裂隙硬粘土在开挖工程中的强度衰减。

| Abstract: | In this paper the geologic cause related to the engineering properties of fissured leek is pointed out. Based on the results of test the parameters of the shear strenght are obtained and the defect of these parameters is also discussed. Simutaneouely the suitability adopting field vane test and standard penetration test to get the shear strength in situ is talked over. Due to the fissure in leek author put forward the back-calculation based on the slip surface in situ to determine the actual shear strength. Finally, an example of landslide to show the influence of fissured leek on engineering practice is given. |
