高速铁路隧道沉降变形分析方法的研究
Research of analytical method for tunnel settlement and deformation of high-speed railway
摘要
Abstract
Based on assessment projects of deformation monitoring of Chang-Zhu-Tan intercity railway project, the law of development for tunnel settlement about Chang-Zhu-Tan intercity railway is investigated. According to measured data, we found that the settlement amount of the tunnel is generally small, Using the hyperbolic fitting and the gray prediction mod-el for the same set of settlement data of the comprehensive II standard team of Chang-Zhu-Tan, the differences between measured and predicted settlement are analysed, and the applicability of two models are compared. The results show that:The simulation of hyperbolic settlement requires a lot of samples, it can be used as a method to assess the tunnel settle-ment. However, the high simulation accuracy is only valid in the case of a small number of incremental cumulative settle-ment. Grey prediction desired sample is small, and has simple operation and high simulation accuracy. Comparing with the hyperbolic fitting, gray prediction has higher precision and universality.关键词
