Application of Soil-nailing Protection Technology in Complex Conditions

  • 摘要: 介绍了在临近人防通道复杂条件下土钉支护的设计,为确保人防的安全,采用国际通用FLAC岩土工程分析软件对设计方案进行了比较和优化,预测了支护的变形和土钉内力,并进行了现场实测。通过实测数据与理论计算值、数值模拟值的对比分析,表明土钉实际受力明显低于现有常规计算方法计算出的数值,而略大于FLAC数值模拟结果。论证了FLAC用于土钉支护变形、土钉内力分析的可行性,指出了现有计算方法的不足。
    Abstract: The Design of soil-nailing prop-up under complex conditions near civil defence passage is introduced. In order to ensure the safety of civil defence engineering, the analysis software of FLAC geotechnical engineering commonly used in the world is adopted to compare and optimize the design schemes and to predict the deformation of the protection and the internal force of the soil nail. The comparison analysis among the measured data, the theoretical calculation value and the numerical simulation value shows that the exerted force on the soil nail is obviously lower than the calculated results by conventional calculation method and slightly bigger than the results of FLAC numerical simulation. The feasibility of applying FLAC to analyze the protection deformation and internal force of soil nail are demonstrated. At the same time, the defects of the present calculation method are pointed out.
