摘要
针对黄土地基承载力影响因素复杂的特点,基于模糊综合评判原理提出了黄土地基承载力模糊综合评判的确定方法。通过对黄土地区大量实测资料进行统计分析,构造了隶属函数形式,建立了承载力评价模型,权重采用了主观和客观因素相结合的综合权重原则。工程实例验证表明,用该方法确定的承载力更客观、全面,精度明显提高。
Considering the complex features of influencing factors on the foundation bearing capacity of subgrade in loess region, this paper proposes fuzzy synthesis evaluation method on the foundation bearing capacity in loess region based on fuzzy synthesis evaluation theory. With the results of actual plate loading tests in loess region, the membership function is built, and the model is developed for the evaluation of bearing capacity. Its synthetic right weight includes both subjective and objective right weight. The application resuts show that this method is more objective, comprehensive with high accuracy. 6 tabs, 1 fig, 6 refs.
