摘　　要：结合某高档综合楼12 m深基坑开挖施工过程的现场监测结果,分析了深基坑开挖引起支护结构和邻近土体水平位移的形态和发展过程,及其与地基土质条件、基坑开挖施工工序之间的关系,并统计了最大水平位移发生的位置。结果表明,土体的水平位移大于支护结构的水平位移;最大水平位移发生在坑底附近;底板浇筑完成后,水平位移仍在发展,但增量有限。Field monitoring is carried out during the construction of a 12 m deep excavation for the foundation of a luxury complex building.The characteristics and the development of the lateral displacements of retaining wall and its surrounding soils are analyzed.Also investigated are the displacement-related ground conditions and construction process of the deep excavation,together with the locations where the maximum lateral displacements occur.It is shown that the lateral displacements of soils are greater than those of retaining structure.The maximum lateral displacements occur near the base of the excavation.After the construction of foundation base plate,the lateral displacement still develops,though its increment is limited.
