摘　　要：福州新都会花园广场基坑开挖和支护结构的设计与施工始于1992年。基坑平面面积7000 m2,开挖深度10.7 m。支护结构采用内支撑柱列式排桩,内支撑采用现浇钢筋混凝土梁。基坑开挖在土体水平位移监测的指导下进行,分东西两部分进行。本基坑工程进展顺利,未发生任何意外,对周围建筑物的影响较小。A deep excavation case study on a project in Fuzhou City was presented. The excavation covers a plan area of about 7000 m^2 and extends to a depth of 10.7 m. The site is underlain by soft soils composed of recent fluvio-marine sediments. The design system consisted of retaining soldier piles with two levels of internal bracing struts. The construction were constructed under the guidance of site monitoring. The design and construction of the retaining structures were discussed. It is shown that soldier piles with internal bracing system are appropriate retaining structures for deep excavations in Fuzhou.
