离心机作为一种自重加载的工具是其他任何加载手段所无法比拟的,离心模型试验在岩石力学和土力学方面有着广泛的应用前景,这些我和该文的作者是共识的。但对文章提到的关于离心机作滑动试验(抗剪强度储备)的一些观点及实例所提到的问题,笔者有一些不同看法,在此提出与文章作者商榷。因文章提到的是单一滑动问题,这里也仅就单一滑动面而言,不讨论双向滑动等更为复杂的问题。 1.强度储备系数:强度储备系数是评判建筑物是否安全的一个非常重要的数据,特别是对于一些大型工程,除进行理论计算外,往往还必须进行物理模型试验加以验证。这里所指的强度储备包括了抗拉、抗压及抗剪的强度储备,但对于基础内存在软弱结构面及缓倾角裂
As a kind of self-heavy loading tool, centrifuge is unmatched by any other means of loading. Centrifugal model test has a wide range of application prospects in rock mechanics and soil mechanics. These I and the author of this paper are in agreement. However, some of the views mentioned in the article on the centrifuge sliding test (shear strength reserve) and the problems mentioned in the examples, the author has a number of different views, and here to discuss with the author of the article. Since the article mentions a single-slide problem, the more complicated issue such as two-way sliding is not discussed in terms of a single sliding surface. 1. Intensity reserve coefficient: The strength reserve coefficient is a very important data for judging whether a building is safe, especially for some large-scale projects, in addition to theoretical calculations, it is often necessary to conduct physical model tests to verify. The strength reserve referred to here includes the tensile, compressive, and shear strength reserves, but there are weak structural planes and gentle dip cracks in the foundation.
