摘要
以工程实例为背景,对隧道洞口段施工过程中围岩的收敛变形,锚杆作用应力,初次衬砌、二次衬砌内的应力与变形,以及衬砌间的压力进行观测,取得大量的试验数据,并结合施工过程进行分析,为隧道衬砌设计和施工的安全可靠性提供科学依据和技术指导,为进一步的工程研究积累资料.
In this paper, a real engineering was taken as the example. Many mechanic parameter were tested, such as the convergent deformation of tunnel surrounding rock, the anchor stresses, the stresses and deformation in initial and second shoring system, and the pressure between the two shoring system, etc. And based on these datum, the author analyzed the mechanic property of shoring system combined the process of tunnel construction. All these provided the beneficial reference for design and construction of the same kind of engineering.
