| Abstract:Through the testing examples of uplift piles for deep excavation bracing in the complex formation of coastal area, the test parameters and methods are introduced, as well as the uplift pile construction technology of deep excavation bracing, such as boring technology in rockfill formation with soil, core sample taking at the end of pile and pile hole cleaning. The test data show that the test parameters of uplift are reliable and can meet the requirements of float resisting capability of the structure design, which provides the data support for the application of uplift pile in deep excavation. |
