光阳重车大会师西安站纪实

正7月7～8日,西安,光阳摩托重车大会师和第四届两岸摩旅一带一路丝路行第二梯次的起始地,而终点是那2600 km外的敦煌。试想,有多少人想在这炎热暑期出去走走,走一条可以涤荡心灵的路,走一条可以记录进人生的路。光阳设计的这条由西安出发,经天水、兰州、西宁、张掖、麝峪关后到达河西走廊的最西端,一路上去感受饱经千百年风雨后方才积淀而成的厚重的历史文化,去看看小时候在课

砂板岩互层隧道掌子面突水灾变发生模型试验研究

To investigate the catastrophic mechanism and pattern of water inrush in tunnels in sand-slate strata, this paper takes the Xinping Tunnel on China-Laos Railway as the study case, and through model tests, reproduces the catastrophic occurrence and evolution process of the water inrush in the progressive failure of slate aquifuge, so as to analyze the changing pattern of the stress-strain characteristics of surrounding rocks, seepage pressure and flow rate with the decreasing thickness of the aquifuge. The results show that: (1) The water inrush in the sand slate strata would experience three stages: seepage, inrush and attenuation, which is essentially a gradual evolution process where, under the action of excavation unloading and stress and seepage coupling, fractures in the weak parts of the aquifuge gradually expand and break through until inrush channels are formed and the stability of the aquifuge loses gradually; (2) The stress-strain curve of the surrounding rocks and the relationship between the seepage pressure and flow show significant precursor and stage characteristics, and their changing patterns reflect the breeding, devel⁃ opment and evolution process of the disaster; (3) A sudden change point exists in the changing process of the seep⁃ age pressure and flow rate, and this sudden change point can be seen as the characteristic point of degradation in the water-blocking capacity of the aquifuge. The aquifuge thickness reflected by this point can be seen as the critical safety thickness of the aquifuge. © 2023 Editorial By Modern Tunnelling Technology. All rights reserved.
