岩土工程学报2008年7期刊登了题为“斜坡演化的燕尾突变模型研究”[1]的文章。笔者意欲在以下几点与原文作者商榷。(1)介质1本构模型中的问题原文滑坡的分析模型如图1,非均匀软弱夹层厚为h,夹层到坡表面的平均距离为B,坡体重量为W,坡表面的平均位移为a。夹层由两种介质组成,其中介质2具有应变软化特性,l h,ls为夹层中两种介质的统计长度。
Chinese Journal of Geotechnical Engineering, 2008 (7) A paper titled “Research on Swallowtail Catastrophe Model of Slope Evolution” was published [1]. I would like to discuss with the original author in the following points. (1) Problems in constitutive model of medium 1 The analysis model of the original landslide is shown in Fig.1. The average thickness of the non-uniform weak interlayer is h, the average distance from the interlayer to the slope surface is B, the weight of the slope is W, and the average displacement of the slope surface is a. The interlayer consists of two media, of which the media 2 has strain softening properties and l h, ls is the statistical length of the two media in the interlayer.
