| 摘 要： | 由于边坡挡土墙设计失误、基础施工影响及原事故处理不当等原因,造成施工地段桩基-地基土-挡土墙体系超量位移,从而导致桌坡顶住宅楼开裂。通过在相应部位施工钻孔灌注桩,完善相关排水、隔水系统等措施,使住宅和边坡达到稳定。由此,应引起工程界对坡顶建筑-基础-地基土-边坡支护体系相互作用机理相关问题的重视。

| Abstract: | Owing to incorrect design of slope retaining wall, influence of foundation construction and original incorrect treatnient measures, super-displacement is produced in construction section among certain pile foundation-foundation soil-slope retaining wall system. Consequently, the wall of dwelling house on the top of slope split open. The dwelling house and the slope are stabilized by construction of piles in pre-bored holes and improvement of dewatering & cut-off drainage measures. As a result, people should pay attention to the problems about interaction mechanisms among building on the top of slope-foundation-foundation-foundation soil-slope retaining wall system. |
