| 中文摘要: |
| 基于顾桥煤矿表土段拟采用冻结法进行施工，为取得冻结粘土流变性参数，以顾桥煤矿东风井深厚粘土为研究对象，进行人工冻土单轴蠕变实验，并根据实验结果分析出冻结粘土的稳定蠕变方程，同时运用相关理论知识和H.A.崔托维奇提出的数据处理方式分析实验数据，推导出人工冻结粘土的长期强度方程。该方程不仅为井筒冻结设计和施工参数选取提供了重要依据，而且有助于进一步研究淮南地区具有代表性深厚粘土层的冻结力学性能，同时为今后相关的建设提供借鉴。 |
| 英文摘要: |
| Freezing Method is to be applied in topsoil segment in Guqiao Coal Mine. In order to obtain rheological parameters of frozen clay, we take deep clay layers of Dongfeng Shaft Guqiao Mine as subject to do artificial frozen soil uniaxial creep experiments from which stable creep equation is derived. Experimental data is ananlysed by applying relevant theory and statistical methods proposed by H.A.Цуй Миятович. Data is processed and derive long-term strength equation of artificial frozen clay. The equation not only provides an important basis for shaft freezing design and construction parameter selection, but also helps to further research of freezing mechanical properties of deep clay layer of Huainan area. It can provide reference for future related construction. |
