SMW工法桩采用三轴水泥搅拌桩,内插型钢劲性材料成型,在地铁的围护结构中广泛采用。规划杭州地铁5号线与在建紫金港隧道斜交,考虑到未来地铁盾构机的施工而在相交区段采用了SMW工法桩。本文通过对比分析在一个开挖断面上的SMW工法桩与地连墙在基坑工程施工过程中水平位移的理论计算值与实测值的变化规律,分析墙后不同距离内沉降量变化值,以及对比施工过程中内支撑轴力的理论值与实测值的变化情况,研究采用SMW工法桩与地连墙的协同变形能力,为相似工程提供参考。
SMW method pile with three-axis cement mixing pile, insert the shape of steel reinforced materials, widely used in the envelope of the subway. Plan the Hangzhou Metro Line 5 and Zijin Harbor tunnel under construction bias, taking into account the future construction of subway shield construction in the intersection of the section SMW method using pile. In this paper, through comparative analysis of the theoretical and measured values of the horizontal displacements of the pile in the excavation section of the SMW method and the continuous wall in the process of foundation pit excavation, the variation of the settlement in different distances between the walls and Contrasting the changes of the theoretical and measured values of the internal support axial force in the process of construction, the synergetic deformation ability of the pile with the wall connected by the SMW method is studied to provide references for similar projects.
