布拉格举行了“1988年地下结构”国际会议,会议对改善地下结构施工、应用新奥法和在含水不稳定地层中开挖隧道的问题给予特别的关注。 在结构研究和改进方面,越来越多地利用建立《土—衬砌》系统数学模型,最大限度接近实际。在物理模型中采用相似材料法进行试验研究,解决了施工安全、防止坍方和坑道变形、地表破坏等问题,保证了衬砌的可靠性。 会议指出有限单元法的应用前景。这一方法可以
Prague held the International Conference on Underground Structures 1988, which gave special attention to the improvement of the construction of underground structures, the application of the New Austrian Law and the excavation of tunnels in unstable water-bearing formations. In structural research and improvement, more and more use of the establishment of “soil - lining” mathematical model system, the maximum close to reality. In the physical model, a similar material method is used to carry out experimental research, which solves the problems of construction safety, prevention of collapse and tunnel deformation and surface damage, and ensures the reliability of the lining. The meeting pointed out the application prospect of the finite element method. This method can be
