摘要
本文介绍了一种人类工程活动诱发的地质灾害现象——矿区地下采空引起地表不均匀沉陷及地面建构筑物的开裂破坏。着重分析了据计算已被认为是稳定区内所产生的破坏现象,指出:区内岩土体的工程地质条件是产生各种破坏现象的制约因素,地表及地下水的活动是重要影响因素,而人类工程活动则是诱发因素。对此不可不引起重视。文中还提供了一些防治该类地面破坏的有效措施。
The main causes of breaking damage of surface buildings in estimated steady region in mining area arc as follows: (a) the effects of mining; (b) the influences of physical and mechanical properties of rock mass and soil body; (c)effccts of water; (d) effects of the collapse post.The comprehensive analyses shows that the engineering geological characteristics of rocks and soils have the key effect to the surface settlement and it must be considered first when estimate the safe mining boundary. The clTcct of underground water and surface water are also important. The surface settlement in coal mining region is produced by human engineering activities, natural geological condition and series of natural effects. The damage of the surface buildings is interrelated to the underground mining. The damage of rocks and soils in the roof of mined-out area and the surface settlement must be considered as a whole.
