【摘要】 本文针对采动框支结构的受力特点，首先分别对框支结构作用在刚性条形基 础、柔性基础、桩基础三种基础形式进行了受采动影响的理论分析，根据有关文 献，总结出适合于刚性条形基础、柔性基础、独立基础的设计“效应结合设计法”， 并与实验进行对比论证。 其次，根据采动区框支结构的特点，对其柱弹塑性稳定性进行了研究［24］， 通过对采动区框支结构弹塑性的分析与论证，提出了采动区框支结构的稳定性校 核公式，并与试验进行对比，论证可行性，完善和补充了钢筋混凝土的“弹性核” 理论，为采动分析提供了依据。 另外，本文对框支结构在采空区的墙体变形进行了分析并用条带逼近法，推 导出其内力和变形，并编制了墙体变形分析程序。 第四，根据我国是一个多地震国家，而且矿区有80％以上位于地震区，因 此本文提出在采动区即抗采动、又抗震的双重保护，双者是对立统一的；本文基 于双重保护原则，首先对框支结构在地震作用的受力特点，通过对比分析计算， 提出了这类结构物的底层剪力增大系数，在理论和实用上完善了我国现行抗震设 计规范，然后着重讨论了采动区在地震作用基础滑动层的滑移变形控制与计算分 祈，并编制了地震作用下基底滑移分析程序； 最后，提出了建筑物抗变形及保护具体措施，发展和补充了采动区混合结构 变形控制理论。更多还原

【Abstract】 First,Progressing analyses of mining effect aiming at three kindsof foundations including rigidity strip foundation,flexible foundationstake foundation aiming at suffering characteristic of Frame-work supportby column in mining in this paper. Basing connecting literatures,Summing up "domino effect combining design method" for rigidity stripfoundation,flexible foundation,stake foundation and contrasting anddemonstrating with experiments.Next. According to characteristic of Frame-work,canying throughresearch about elasto-plastic stability in mining area,through analysesand argumentation about frame-work support by column in miningarea,putting forward checking formula about stability of frame-worksupport by column in mining area, and Canying through contract toexperiments. Reasoning feasibility,making up reinforced concrete"elasto-nucleus" theroy,offering base for mining analyses.Besides, Putting up analyses at wall distortion of frame-worksupport by column in mining area,and, Educing its intemal-force anddistortion with strip aPproaching method and, working out analysesprogram of wall distortion.Fourthly, according that our country is a excessive earthquakecountry,and 80 perceflt of them lie at earthquake section, So, puttingforward double protect of contradict mining and contradict earthquake inthe paper, both of them are opposing and uniform, basing on doubleprotect principle. First, Suffering characteristic of frame-work byearthquake effect, plltting forward bottom sheering force augmentcoefficient of this kind structure substance, through contrast and analysesand calculate,perfecting our counry present design criterion of contradictearthquake,then,emphasizing on discussion about slippage distortioncontrol and calculate and analyse,making up floor analyses program byearthquake effect.Finally putting forward building of contradicting distortion andprotect material measure, developing and supplying mixing structuredistortion controlling theory in mining area.更多还原
