[交流] 一段摘要翻译

【摘要】结合高速公路路基膨胀土的分类实践,通过对影响膨胀土胀缩的主要因素进行了分析,根据《公路路基设计规范》对膨胀土的评判标准,将投影寻踪聚类模型应用于膨胀土的综合评判中,建立了路基膨胀土判别与分类的投影寻踪综合评价模型。该模型采用粒子群算法寻求最优投影方向,根据投影特征指标值对膨胀土进行分类评价。研究表明,该技术对膨胀土分类,避免了评判专家主观确定权重,评价结果客观准确、方法简单,为膨胀土的分类提供了一条新的途径。
【关键词】膨胀土expansive soil;投影寻踪projection pursuit;粒子群算法particle swarm optimization;公路路基highway subgrade; 分类classification;

Combining with the classification experiment of expansive soil of the expressway subgrade, through the analyzation of the main factors that effects the Swell-Shrinking of  expansive soil, and based on the judgement standards in , the systematic evaluation model of the projection pursuit for judging and classifing expansive soil of the subgrage.
In the model, particle swarm optimization method was adopted to determine the best project direction, and then classifying evaluations were performed according to the index value of the project features. The results showed that, utilizing this technology to classfy the expansive soil, the unreasonable subbjective judgement of the evaluation professional can be avoided, and the evaluation results were objective and exact with the method being simple, therefore, this technology provided us a new method for classfying the expasive oil.

Key words: expansive soil;projection pursuit;particle swarm optimization;highway subgrade; classification

为了跟key word符合,楼主把其中的expressway改成highway吧,呵呵,请检查哦
