人工连续墙在地铁基坑中的应用

【摘要】 人工连续墙是广州地铁二号线中大力推荐的一种基坑围护结构 ,具有结构稳定、防水效果好、造价低、施工方便等优点。用 2D σ有限元计算软件分析了该结构的桩 (墙 )体位移、梁的轴力及弯矩 ,并将计算结果与实测结果进行了对比 ,二者吻合较好更多还原

【Abstract】 Man-dig diaphragm-wall is greatly recommended in Guangzhou Metro Ⅱ.This kind of structure is stable and convenient to be constructed, and has advantages such as good watertight effect,low expenses.The finite element calculation software 2D-σ is applied to analyze the displacements of piles(walls), axial stress and bending moment of beams.The calculation results are identical with the measured results well.
