The effectiveness of RI cone penetrometers has been demonstrated by using it in different environments. And the data obtained through these penetration tests are effectively employed in the foundation engineering works. The main conclusions derived are as follows :1. These newly developed cone penetrometers have been used effectively in various soil environments, such as the reclaimed land with high cloride content, normal clay deposit to site characterized by very high water content.2. The presence of chloride ions in the soil can lead to the underestimation of the natural water content of the soil. Therefore care must be taken when the RI cone is employed in the marine environment or the marine deposits.3. Soil improvement work can be continuously monitored through these cone penetrometers. This is done by checking the void ratio and the density profiles at the construction site.4. The data obtained from these cone penetrometers can offer the useful information about the conditions of a clay foundation. We can use this set of information as input for finite-element analyzes.5. Encouraged by the results obtained above, we believe that by deploying these cone penetrometers at various stages of construction process, practicing engineers can build-up a data base which can be used in calculating the settlement of a clay foundation.

RI 锥入度计的有效性已通过在不同环境中的使用得到证明。通过这些渗透测试获得的数据在基础工程中得到了有效的应用。得出的主要结论如下： 1．这些新开发的锥入度仪已在各种土壤环境中得到有效使用，例如高氯含量的开垦土地、正常粘土沉积物以及含水量极高的场地。 2．土壤中氯离子的存在会导致低估土壤的自然含水量。因此，在海洋环境或海洋沉积物中使用RI锥体时必须小心。3．通过这些锥入度计可以连续监测土壤改良工作。这是通过检查施工现场的空隙率和密度剖面来完成的。4。从这些圆锥贯入仪获得的数据可以提供有关粘土地基状况的有用信息。我们可以使用这组信息作为有限元分析的输入。5．受到上述结果的鼓舞，我们相信，通过在施工过程的各个阶段部署这些锥入度计，实践工程师可以建立一个可用于计算粘土地基沉降的数据库。
