摘　　要：某高层建筑基坑施工中,采用钢格构柱十字钢梁组合的塔式起重机基础,其做法是在混凝土工程桩中插入钢格构柱,土方开挖前焊接十字钢梁并安装塔式起重机,挖土时形成格构式塔机基础,在保证工期、节省费用方面效果很好。During foundation construction in a high-rise building project, combined lattice column and cross steel beam were used as tower crane foundation. This method inserted steel lattice column into the concrete pile, welded the cross steel beam and installed the tower crane before earth excavation and formed the lattice tower crane foundation during earth excavation, successfully guaranteeing the construction schedule and saving construction cost.
