【摘要】 通过对两淮地区新建十几个冻结法施工井筒温度场的实测数据样本分析,较全面地考虑影响人工冻土温度场发展的诸因素,利用智能方法对大量样本的学习,形成了一个大型的能预测温度场的开放式网络结构。并与实测数据比较,表明该方法对未知温度场的发展能进行较好地预测,对井筒开挖时间、开挖方式及井壁结构的确定有重要意义。更多还原

【Abstract】 After analyzing the sample data of temperature field of a dozen of mines in Huainan and Huaibei,considering the elements which effect the development of temperature field and applying intelligent method to studying the sample,a great open network which can forecast the development of artificial frozen temperature field is formed.Through the comparison with the real date,it proves that the method can forecast the development of unknown temperature field.It is important to forecast the temperature field for determining the excavating time,the election of excavating method and the structure of wall of mine.更多还原
