Aiming at converting the loading problem in space into the one in plate , the theories of loading distribution along crosswise are applied 作者对空间桥跨结构中的荷载横向分布理论进行了系统地论述。
Therefore , those formulas are not very convenient for application , and are very difficult to be compared to select the most suitable one . although the different bonded materials behave disagreement with each other , nevertheless , the calculating theory of load capacity is similar 但是,上述这类加固方法在承载力计算上有很大的相似性,完全可以用一个统一的通用公式进行计算,这有利于选择最佳的加固材料。
At the moment , the basic theory of loading mechanics is always used to search the problem of rock mass failure , but unloading and loading have different stress road and different destruction effect , so there are much difference in destruction mechanics and deformation between unloading and loading mechanics , if loading mechanics is used to study the destruction property of tunnel excavation and its stability , the result which agree to real engineering cannot be obtained 目前一直沿用加载岩体力学方面的基本理论研究失稳问题,但本文认为:由于卸荷与连续加载具有完全不同的应力路径和破坏效应,在破坏机理、二者引起的岩体的变形和破坏特性方面都有很大的不同,因此用加载力学来研究开挖卸荷破坏的力学特性及其稳定性,这显然不能得出与实际工程一致的结果。
