摘要
在将军沟隧道出口工区塌方洞段地质调查基础上分析了隧道塌方的影响因素,根据隧道塌方的实际情况,结合当前隧道施工技术,确定了以"稳固塌方体、加固塌方影响洞段、在超前小导管超前预支护条件下采取台阶法及时支护"的施工措施和方案,从而积累了隧道塌方处理经验。
The influencing factors of tunnel collapse were analyzed at the base of geological survey of Jiangjun ditch tunnel export work area collapse cave section, based on the practice situation of tunnel collapse, combining with the current tunnel construction technique, the construction measurement and schemes of fixing collapse body, reinforcing collapse influencing cave section and adopting step method supporting timely under the condition of leading conduit advance pre-support, so as to accumulate the experiences of treating tunnel collapse.
