1、中國(guó)科技論文在線http://www.paper.edu.cn#斷層突水非線性滲流-應(yīng)力耦合研究122*郭惟嘉，趙金海，白麗揚(yáng)（1.山東科技大學(xué)礦山災(zāi)害預(yù)防控制省部共建國(guó)家重點(diǎn)實(shí)驗(yàn)室培育基地，青島266590；52.山東科技大學(xué)礦業(yè)與安全工程學(xué)院，山東青島266590）摘要：針對(duì)斷層水突出日益嚴(yán)重的問(wèn)題，為揭示斷層水突出過(guò)程中的流固耦合作用影響下突水不同時(shí)刻，不同階段上承壓水運(yùn)移規(guī)律，在斷層破碎帶中應(yīng)用非達(dá)西流動(dòng)方程并考慮應(yīng)力作用和孔隙水壓力作用對(duì)斷層帶中巖石力學(xué)參數(shù)影響，應(yīng)用comsol軟件建立含水層-斷層-工作
