| 摘 要： | 通过岩体空间应力测试分析出渝怀铁路黄草隧道存在极高地应力,应力比均小于4,为按照新奥法原则进行设计、施工提供了可靠的实测数据。经过变更设计改变衬砌类型和支护参数,保证施工安全。黄草隧道岩体应力测试结果可为今后软岩地质、极高地应力地质的隧道设计、施工提供借鉴。

| Abstract: | Extremely high ground stresses exist around the Huangcao Tunnel in Yuhuai Railway found from rock mass space stress test and analysis.Stress ratio is less than 4.The test results supply reliable actual measurement data to design and construction by NATM.Safety of construction and management can be assured by design alteration such as changing lining style and support parameter.Tunnel design in soft rock geology and extremely high ground stresses geology can offer higher experience from the data. |
