单一关键层结构与上覆厚沙土层耦合作用研究
Coupling effect between single key strata and the overburden thick sandy soil layer
摘要
Abstract
Through the simulating model test, the coupling effect between single key strata and the overburden thick sandy soil layer is studied, the failure character of thick sandy soil layer is obtained, and the load transmitting law on the key strata(key block) is found. This research is of a basic role in dynamic roof structure theory.关键词
