| 摘 要： | 在岩溶富水地段,隧道衬砌实际上处在围岩应力场和渗透渗流场双场之中,渗流场的存在会导致围岩自稳能力降低,从而增加了围岩对衬砌的压力,同时渗流场的存在也会对隧道衬砌产生了渗透压力,研究了大干溪Ⅰ号隧道衬砌水压力,探讨了在渗流场和围岩应力场相互耦合作用下衬砌内力的变化情况,对富水段隧道衬砌的设计和施工有一定的借鉴意义。

| Abstract: | Tunnel lining in fact is in the surrounding rock stress and osmotic flow field of double field in the karst water-rich, seepage field leads to lower self, thus increasing the pressure of surrounding rock on the lining, and the seepage field are also will produce the osmotic pressure on tunnel lining. This paper investigates Qing Ping water pressure on tunnel lining, discusses the change of internal force of lin- ing stress field coupling in seepage field and the surrounding rock, have certain reference significance for design and construction of rich water section of tunnel lining. |
