摘要

研究了Wu-Bauer亚塑性模型参数试验确定方法及其存在的问题。根据单形调优法，对模型参数确定方法进行了改进，并通过三轴固结排水试验、侧限压缩试验和加卸载试验进行了验证。分析表明，该方法可有效地确定模型参数。最后分析了Wu-Bauer亚塑性模型的优点和不足之处。

Abstract

Method of determining parameters in Wu-Bauer hypoplastic model and its defect are discussed. According to simplex designs in optimization

amelioration of parameter determination is made. The method is proved by virtue of triaxial consolidated drained test

oedometric test and load -unload test. It is shown that this method can ascertain the parameters. The merit and demerit of Wu-Bauer hypoplastic model are analyzed.
