The comprehensive supporting scheme of bored cast-in-place piles plus prestressing anchor cables， cantilever pile support and slope grading is designed for the foundation pit of Beijing Shiyuan Town Reception Center according to the geological conditions. Analysis is conducted of the change rules of the horizontal and vertical displacement of the pile， the surface settlement and the bolt tension through monitoring the horizontal and vertical displacement of the top of the supporting structure， the ground settlement around the foundation pit， the deep horizontal displacement of the supporting structure， and the anchor bolt tension. At the same time， the monitoring data are summarized to provide the basis for the future design.
