监控量测技术在黄土大断面浅埋隧道中的应用

Actual application of monitoring measurement technology in large-section and shallow loose tunnel

结合西宝客专铁路小村隧道地质情况,通过施工过程中持续监控量测,对量测数据选取双曲线函数、对数函数求出回归曲线方程,进行实时分析、阶段分析,将分析结果反馈于施工,提出指导施工和优化原设计的建议,保证了小村隧道施工过程安全,圆满完成了西宝客专铁路重点工程隧道修建任务。

Combining with the geological conditions of Xiaocun tunnel on Xi-Bao passenger special railway line, through continuous monitoring measurement in construction process, the paper selects hyperbolic function and logarithmic function for working out the regression curvilinear equation, carries out real-time analysis and phase analysis, and makes an feedback to the construction with analysis results, and puts forward suggestions for guiding the construction and optimizing the original design. As a result, it guarantees Xiaocun tunnel construction security and successfully finishes the major engineering tunnel repairing and construction task of Xi-Bao passenger special railway line.
