混合结构房屋抗采动设计中若干问题的探讨

Some Respects on Anti-mining Design of Houses with Mixed Structure

本文针对在煤矿采动区兴建砖混结构房屋,探讨了提高其抗采动、抗变形能力的方法和措施。

Based on practice, this paper discusses a new calculation method on aditional inner forces of houses with maxed structure, harmonious condition of base stress at connective locations is taken into consideration,calculation process of design and its key points——establishing method of equilibrium equation are given, advantages of the design method are also pointed cut. The paper analyses force statusof base slide layer under influences of different horizontal deformations and curvatures on ground surface, setting conditions considering of optimal efficiency of the slide layer in anti-deformations induced by mining; influences of the house height changes to aditional inner forces in structures are also analysed, therefore theoretic foundation on reducing of reinforcement costs and on selections of anti-mining measures is given, a design theory for improving of anti-deformation houses is further discussed.
