摘要
深埋隧道洞壁的稳定问题是一个复杂的动力学问题。为了研究隧道洞壁的稳定问题,人们提出了许多隧道压力的计算方法,尽管在隧道稳定领域有很多分析方法,但人们在隧道设计与施工过程中,仍然非常重视已有的各种经验和施工现场的原位监测工作。以大量的隧道施工原位监测数据为依据,提出了基于引力场的深埋隧道洞壁动态稳定性分析方法,给出了相应的计算公式和应用实例。
The stability of tunnel pit-wall in the depths underground is a complicated dynamic problem. To study the stability of tunnel pit-wall, many calculation methods of the tunnel pressure are put forward. Although there are many analysis methods in tunnel stability field, all sorts of exiting experiences and local measured work in construction spot are highly regarded during tunnel design and construction process. According as plentiful tunnel local measured data during construction, the dynamic stability analysis method of tunnel pit-wall in the depths underground based on gravitational field is put forward. Corresponding calculation formula and application examples are offered.
