Measurements and Numerical Simulation of Stress in Anchors of Tucheng Project

The stress of anchor in retaining structure reflects the value of earth pressure in some degree. So carrying on in-situ measurements of anchors stress, the value and distribution of earth pressure will be investigated by analysis on actual data. It has important and practical significance in optimizing design of retaining structures of deep foundation pit. Taking the practical project for example, the actual stress of anchor during tensioning and fixation is measured and analyzed. With the FLAC numerical simulation, the calculation method of earth pressure on retaining structure is discussed.
