| 摘要: |
| 【目的】为了缓解采后土地重建水利工程的土地资源短缺问题，对不良地质再建农田灌溉渠道可行性的风险级别进行评价。【方法】筛选了包括采空区风险、外在风险、采砂区风险和渠道内在风险4个方面共13个评价指标，提出了用云模型改进“3标度”AHP（层次分析法）-传统物元的风险评价方法。【结果】①对于最终的评价结果，根据权重来看，应重点关注采空区及采砂区风险，而对于采空区风险则需重点关注采空区停采时间，采砂区风险需重点考虑采砂区距离渠道边坡的距离；②从单向因子风险评估情况来看，需重点考虑采空区埋深及当地地基土粘聚力的影响。在施工前需要对相关风险因素进行处理和预防，采取相应的措施后，在保证安全的前提下进行渠道施工。【结论】实例应用表明，与相关文献中的方法对比，本文的评价结果更加客观、准确，具有更好的适用性，对于不良地质条件下的农田灌溉渠道施工有重要的指导作用。 |

| Abstract: |
| 【Objective】 Constructing hydraulic engineering projects in tailings of sand mining faces many challenges that are absent in other areas. This paper presents a method to evaluate the risk and feasibility of building farmland irrigation channels in such regions.【Method】 We consider 13 indicators in the evaluation, including goaf risk, external risk, sand mining area risk and channel internal risk. A three -layer analytic hierarchy process (AHP) method based on cloud model is proposed to calculate the evaluation. The results are compared with those calculated using traditional matter-element risk assessment method.【Result】Goaf and sand mining area risks should receive more attention, particularly the time of mining termination and the distance between the mining area and the slope of the channels to be constructed. One-way factor risk assessment shows that the impact of the buried depth of the goaf and the cohesive force of the foundation soil are important factors to be considered. Assessing all risks and having mitigation plans in place is essential before the construction.【Conclusion】Compared with traditional methods, the proposed method is more objective, accurate, and applicable. It will play an important role in helping design farmland irrigation canals in or in proximity to tailings of mining. |
