摘要
以实验室模拟试验为基础,获得了地表裂缝发育的一系列规律,建立了地表裂缝发育极限深度的预计模型,建立了裂缝发育宽度和深度关系的典型曲线.实例证明,预计模型是正确的,具有很大的实用价值.
In order to study the destruction mechanism of the cultivated land by mining subsidence and the reclamation counter measure,we must study the development depth and width of ground fissure caused by mining.Based on laboratory simulation experiment,this paper got a series of laws of ground fissure development,and established a prediction model about the limit depth of ground fissure development,and also established a typical curve about the relation of fissure development depth and width.lt is proved by real example,the prediction model is correct.It has a great deal of practical value.
