地下连续墙作为地下基坑围护加上钢支撑的围护体系已被广泛用于建造地铁车站。在考虑支撑布置设计中,木文就外部条件和基坑宽度、深度等参数相同的情况下,对三道支撑和四道支撑二个方案在计算地下连续墙弯矩、位移和支撑轴力等方面进行对比,其结构配筋基本接近。故在车站两侧建筑物不太密集或相距较远的情况下完全可以减少一道支撑,同样可以达到预期的效果。
The underground continuous wall, which is the enclosure system for the underground foundation pit and the steel support, has been widely used for the construction of subway stations. In consideration of the support layout design, in the case that the external conditions and the pit width, depth and other parameters are the same, in the calculation of the bending moment, displacement and supporting axial force of the underground continuous wall for the three-support and four-support two schemes. In contrast, the structural reinforcement is basically close. Therefore, under the condition that the buildings on both sides of the station are not dense or far apart, one support can be completely reduced, and the desired effect can be achieved as well.
