Application of stress path in consolidating soft clay foundations of large scale storage tanks |
| |
Abstract: | A storage tank with a large capacity of 100,000 steres has firstly been built on soft clay base in Shanghai China. Working on it by a comprehensive ground treatment, such as sand-gravel pile, plastic drainage plate and filling and prepressing, during the process, the method of stress path is practical and effective in monitoring and controlling the stability of the foundation. |
