海底隧道不同防排水条件下衬砌结构开裂情况研究
Study on the lining crack of subsea tunnel in the different conditions of waterproof and drainage
摘要
Abstract
The waterproof and drainage way are not always similar to each other in the different level of surround-ing rock of subsea tunnel,among which the principle of controlled drainage was used in the hard surrounding rock I andⅡ,and the entire plugging method can be applied to the surrounding rock of poor quality,such as the level of Ⅳ and Ⅴ.Based on the XFEM,the actual cracking of Xiamen Subsea Tunnel will be taken in a re-search in different condition of waterproof and drainage,which can be available to provide some useful sugges-tions for the building of other high -pressure tunnels and making cause analysis of lining crack.The research re-sults show that it is not happened to the crack of tunnel lining in the case of controlled drainage of surrounding rock level Ⅱ and the design is reasonable.It also turns out that the outside of arch springing of tunnel lining is cracked in the condition of whole block of surrounding rock level Ⅴ.Both the crushing and cracking of concrete lining will happen under the condition of higher water pressure,which need to be structural reinforced in the rel-evant position of tunnel lining cracks.Besides,based on tunnel lining diseases until now,which mainly are cir-cumferential cracks and located in some parts above the arch wall,it is found that the high water pressure isn’t the main reason of lining cracking of Xiamen subsea tunnel.关键词
