To design safety monitoring system in foundation piles, the number and location of multi-sensors should be optimized, so that comprehensive and reliable stress distribution can be observed. Minimal cost principle should be complied for number optimizing of multi-sensors system. Rationality principle of characteristic position and distribution curve of observed values should be complied for location...
Stress of foundation pile is more sensitive than the other monitoring indexes such as displacement, so it can be observed to show run behavior more efficaciously. Stress components must be separated by influence factors, and stress monitoring model can be built by the relationship of stress components and their influence factors. Wavelet shows good characteristics in time-frequency domain, so it has...
The settlement behavior of pile foundations is an important index for construction control and design verification especially for bridges built on poor hydrologic and geologic conditions. Settlement calculation methods are appraised firstly. Considering engineering conditions and characteristics of pile foundations of the two main piers in the Sutong Bridge, Improved Equivalent Pier Method (IEPM)...
