| 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,本文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】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；结果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] In order to alleviate the shortage of land resources in post-harvest land reconstruction water conservancy projects, this paper evaluates the risk level of the feasibility of rebuilding farmland irrigation channels with poor geological conditions. [Method] A total of 13 evaluation indicators including goaf risk, external risk, sand mining area risk and channel internal risk were screened, and a cloud model was proposed to improve the "3-scale" AHP (Analytic Hierarchy Process)- Traditional matter-element risk assessment method. [Results] Result 1,for the final evaluation result, according to the weight, the risk of the goaf and sand mining area should be focused, while for the risk of the goaf, the stop time of the mining area and the risk of the sand mining area should be focused on. The distance between the sand mining area and the slope of the channel needs to be considered; Result 2, from the one-way factor risk assessment situation, the impact of the buried depth of the goaf and the cohesive force of the local foundation soil needs to be considered. It is necessary to deal with and prevent relevant risk factors before construction, and after taking corresponding measures, carry out channel construction under the premise of ensuring safety. [Conclusion] The example application shows that, compared with the methods in the relevant literature, the evaluation results of this article are more objective, accurate, and have better applicability, and play an important role in guiding the construction of farmland irrigation canals under adverse geological conditions. |
