Application of circular truss internal bracing in excavations engineering

  • 摘要: 结合深基坑支护工程实践,在软土基坑中采用圆环桁架内支撑,采用二维模型对内支撑受力计算方式进行了探讨,并与监测结果进行对比。监测结果表明,圆环桁架内支撑形式能较好的控制了基坑变形,降低了基坑开挖对周边环境的影响,施工方便且造价较低。
    Abstract: The circular truss internal bracing system is adopted for excavations in soft clay. A 2D numerical model is introduced to analyze the problem. The results of the numerical analysis are compared with the measurements. The measurements indicate that the circular truss internal bracing system can control the deformation well and reduce the infuence on the surrounding environment. Its construction is easy, and the cost is low.
