摘要：塔吊的倾覆荷载较大，采用独立基础时，基础底面积较大，故混凝土用量较大，技术经济指标较低，改用十字梁板式基础力学性能较佳，混凝土投入用量相对较小。

Abstract: The overturning load of the tower crane is huge. Using an independent basis, the bottom area is comparatively broad so that we need use more concrete, and thus the technical and economic indicators are lower. Using the cross-beam board, however, the basic mechanical properties are much better, and less concrete is needed.
Key words: tower crane; cross beam basis; mechanical model

塔吊的倾覆荷载较大，采用独立基础时，基础底面积较大，故混凝土用量较大，技术经济指标较低，改用十字梁板式基础力学性能较佳（见图1），混凝土投入用量相对较小。
