Cause Of Formation Mechanism And Prevention Measure Of Disease Of Highway Tunnel

The study objects of this text are highway and railway tunnel. This text analyze form and mechanism of cause of the tunnel's disease through knowledge theory such as :rock mechanics, soil mechanics, hydraulics, hydrodynamics, chemistry ,and so on. And combine last criterion, rule and engineering practice, provide the tunnel disease's the design of prevention and cure, method of construction, new technique, new material, new craftwork. This text provide some advantageous consult values for tunnel prevention and cure. This text's main fruit and innovate point include:First: Detailed analyzed the leakage's cause mechanism in the aspects of the quality of design and construct and choose the material. And provide corresponding advice about father technique.Secondly: Educed mostly factor of tunnel lining's unstable stability is the circle of freeze and thaw. Moisture's move boost up the destroy of the circle of freeze and thaw. Put forward the tunnel prevention and cure technique about the harm of the circle of freeze and thaw. And these techniques have applied in the engineering.Third: Simulate the ZHEN WU mountain tunnel's lining temperature field in YU QIAN freeway through ADINA numerical analysis software. Provide some theory calculate gist for the cold area tunnel's design.Fourthly: Introduce the tunnel's crack's method of observation and measure. Detailed analyzed the cause of tunnel's crack. Corresponding put forward the tunnel prevention and cure technique. And these techniques have applied in the engineering. Provide science gist for tunnel's crack prevention and cure.Fifthly: Through analyze, educe the nature condition that the lining's masonry quality and concrete variety, the condition water which seep in the tunnel's lining contain erode medium's variety and concentration, environment temperature and humidity and so on is tunnel lining erodent infection factor. Corresponding put forward the tunnel prevention and cure technique. Fetch up the tunnel prevention and cure's shortage.
