| Abstract: | Man-bored grouting pile is used as exterior protected structure for vibration isolation trench, which has a role of rigid vibration isolation. Soft materials, with a function of vibration energy absorption, are filled up in the isolation trench. Distribution of soil pressure around the exterior protected pile and its stability are analyzed, and the design parameters of pile are described. It indicates that the combined system of exterior protected pile and isolation have good effect on isolating vibration and can reduce vibration through the engineering application. |
