摘要
为了研究缓斜底板岩层破断后的后屈曲性态,以鲍店煤矿某变电所硐室为例,将底板隆起量与巷道两帮移近量相结合,确定了缓斜底板岩层的位移幅值以及岩层倾角与两帮相对位移的关系。研究结果表明,巷道底板的位移幅值和相对位移随着岩层倾角的增大而减小,其位移幅值与相对位移呈几何非线性特性。
In order to study the post-buckling behaviors of gentle floor strata breaking, presented an example with Baodian some chamber, combined the hoove-up amount of floor strata and the roadway relative closer, and determined the relationship between them and the rock dip. The results indicate that the hoove-up displacement amplitude and relative displacement of roadway floor decrease with the increase of rock dip, the relationship between both displacement amplitude and relatively closer to value expresses geometry nolinear characteristics.
