A Summary of Testing Study on Cast-in-site Bored Pile in Deep Iced Ground |
| |
Abstract: | ![]() An assessment was made of working principle and bearing capacity computation of cast|in|site bored pile in permafrost zone based on summary of research achievements in recent 30 years on pile foundation at permafrost zone, especially Qinghai|Tibet Plateau by permafrost engineering circle of China. Some advice is raised about factors affecting the bearing capacity of pile foundation and construction technology based on site testing data. |
