基于正交设计的底板注浆加固影响因素试验研究
Experimental research on floor grouting reinforcement influence factors based on orthogonal design
摘要
Abstract
In order to research the comprehensive function and mechanism of influence factors for floor grouting reinforcement effect,the floor crack rate,grouting material mixture ratio and aquiclude thickness were selected as three typical factors.A serious of experiments based on orthogonal design were carried out to simulate the process of mining after floor grouting reinforcement.The floor stress,floor displacement,floor failure depth and floor rock elastic modulus were observed.Sensitivities of these three factors were studied with range analysis method,and the main controlling factor of observation targets was obtained.Results show that,the observation targets change widely in different combinations;the floor crack rate has much to do with floor stress and elastic modulus;the aquiclude thickness has much to do with floor displacement and failure depth;the grouting material mixture ratio also has something to do with elastic modulus of floor rock;intuitive analysis diagram was used to describe the effect law of factors to the observation targets.关键词
