刍议邓肯-张模型的改进性研究

A rustic opinion on Duncan-Chang model's improvement research

邓肯-张模型简单、便于工程应用,但也存在明显的局限性,为此引发国内外学者的一系列改进性研究。首先将近几年的主要研究成果归纳为四大类,并选择典型的改进模型进行简介与分析,然后从工程实用出发,对邓肯-张模型改进性研究的发展方向进行讨论,指出在当前条件下,相对于模型本身而言,模型参数改进的实用意义更大,建议给予邓肯-张模型参数的改进研究更多关注与重视。

Simple and convenient for engineering application as Duncan - Chang model is, there are still obvi- ous limitations, which lead to a series of improvement research both domestically and overseas. First of all, major research achievements in recent years were categorized into four classes, in which typical improvement models were introduced and analyzed briefly. Then based on the perspective of engineering practice, the de- velopment direction for improvement research of Duncan - Chang model were discussed, and the main opinion is as follows： compared with the model itself, improvement in parameters of the model is more effective for en- gineering practice under the existing condition. Finally, it was suggested that improvement research in parame- ters of Duncan - Chang model should be paid great attention.
