摘要

采用美国MTS815型电液伺服岩石力学试验系统，对18块大理岩试件进行了试验，从6种不同围压下岩石应力-应变试验中，获得了岩石强度、剪胀力及体积应变随围压的变化情况规律，揭示了高应力松动、圈巷道围岩大变形的力学机理。提出了破裂岩体围岩与支护相互作用及最佳支护力位于“剪胀二期”初始点的新观点。

Abstract

By using the testing system MTS815 with hydro-electrical servo controllers

the 18 marble specimens have been tested respectively under six different confining pressures; and the changing condition of dilatancy force and volumetric strain in the whole stress-strain process has been obtained. According to the analysis of results obtained in tests

the changing law of rock strength

dilatancy force and volumetric strain with change of confining pressure has been discovered. The mechanism of surrounding rocks’ large deformation of high-stress roadways and the interactive relation of support and surrounding rocks may be brought to light.
