摘要
针对采空区特高压杆塔地基的稳定性问题,根据实地调查资料,对影响杆塔地基稳定性的地质条件、开采条件、边界条件进行了分析,采用层次分析法和模糊综合评价相结合的方法,建立了特高压线路采空区地基稳定性模糊综合评价计算模型,并以实例对特高压杆塔地基稳定性进行了预测。结果表明:该杆塔地基处于危险区,其结果与实际情况相符,该评价方法可应用于采空区杆塔线路的优化设计。
For the foundation stability of UHV transmission tower on goaf, according to the information of field survey, the major geological and mining factors, and boundary conditions that all impact the stability of the UHV transmission tower foundation were analyzed. Based on the AHP and fuzzy comprehensive assessment, built the assessment model of foundation stability on goaf along the UHV line, and then forecasted the founda- tion stability on different types of goaf with an example. The results show that the foundation of UHV tower is in danger zone, and the results conform to the actual situation, this evaluation method can be applied to the route optimum design of UHV transmission tower on goal.
