结合某工程实例讨论张弦梁钢支撑系统在基坑支护中的应用效果,以期对解决当前基坑支护中施工工期长、施工空间较小、环保性差等突出问题有所帮助。对张弦梁钢支撑与砼支撑进行对比,主要说明张弦梁钢支撑系统在施工工期和工程造价上具有明显优势。最后,结合基坑监测数据表明基坑周边变形控制在安全范围内。 Combined with an engineering example, the application of the beam string steel support system in the foundation pit support is discussed in order to help solve some prominent problems such as long construction period, small construction space and poor environmental protection in the foundation pit support. The contrast between the steel truss girder support and the concrete truss support shows that the steel truss truss support system has obvious advantages in the construction period and project cost. Finally, combined with pit monitoring data show that deformation control around the pit within the safe range.
