| In the 1960's, every city in China built quite a lot of human defending subways. But because of they did things in their own ways, and lacked of uniform programming, even because of the low technique level, most of the human defending subways are disused for their uselessness at present. However, as time goes on, these subways are becoming hidden trouble of geological disaster in cities' building engineering in nowadays and in the future. Consequently, it has especial significance in city's architecture area to put up an in-depth study and control the form mechanism of geological disaster of the human defending subway, and to make certain a scientific and efficient solution and measure.This thesis researched the stability of the surrounding rock of the human defending subway systemically on base of a summary of former research of the reconnaissauce to the human defending subway and the research measure of the surrounding rock's stability, and besides, this thesis offered an example of the research of the human defending subway of Hongshiyue borough in Guanghui in Sinkiang province and put up a numerical value simulation to the surrounding rock of the roof by using the analysis program of Lagrange finite difference. The basal channels of thought of the research is: increasing the top load until the room and the overlying strata destroy completely, and research the transformation of the stress and strain around the room and the distributing status of the breach and development disciplinarian. Sequentially, educe the wreck mechanism, and establish a numerical value simulation to the human defending subway, which has different type of surrounding rock and dimension to research and calculate. Ultimately, decided to take action to eliminate the hidden trouble of the human defending subway according to outcome of the above research and the fact of this project, moreover, this thesis treatises idiographic construction measure of grouting of stowing method. |
