罗安达Burity Ultimo基坑支护工程设计与施工
摘要:介绍了安哥拉首都罗安达一座建筑基坑支护结构设计概念和实施过程,实例说明恰当地利用坑侧土层特点,采用钉锚组合支护可使结构平面面积与建筑场地面积之比达到92.5%,基坑竖直开挖深度超过14m而对距坑边0.3～0.5 m的普通民房正常使用与结构安全影响甚微,基坑可观测到的水平位移小于3mm,支护结构经受多次暴雨安全使用2年之久。
Abstract:It's described that the design concept and construction process of a building pit which sites in Luanda,the capital of Angolan. The example shows that structure surface area and building site area ratio 92.5% by the combination of nail and anchor supporting structure. Utilizing the feature of the pit side soil appropriately, the pit excavation depth is more than 14m with vertical slop, and has little no dangerous on normal function and structural safety of dwelling houses which is from the pit at the edge of 0.3~0.5m.The maximum horizontal displacement of the pit can be observed is less than 3mm, The supporting structure endured repeated heavy rains, and its safe periods are past 2 years.
