| 中文摘要:北京世园小镇接待中心基坑依据地质条件确定了钻孔灌注桩加预应力锚索、悬臂桩支护、放坡支护等综合支护方案。通过对支护结构顶部水平位移和竖向位移、基坑周边地面沉降、支护结构深部水平位移、锚杆拉力的监测，分析了桩水平和竖向位移、地表沉降以及锚杆拉力等的变化规律，同时根据监测数据进行了总结，为今后的设计提供了依据。 |

| Abstract: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. |
