Abstract


Huizhou groundwater seal oil storage caverns in Nim Town , Huidong County , Huizhou City , Guangdong Province , is proposed strategic oil reserve pool one , its capacity far the most of such works . This thesis is its object of study , focuses on rock mass quality classification of the water seal oil cavern project . For water sealed oil storage caverns engineering terms , the dam site engineering geological conditions are important factors , including the impact of the construction and operation of the storage caverns security cavern rock mass quality evaluation of care with the guidance of the project cavern excavation and support role. Firstly, to study at home and abroad of the rock mass quality classification ; then in combined engineering geological characteristics of the project , the application of the finite element numerical simulation software Plaxis 3D Tunnel , a three-dimensional geological model to simulate cavern excavation , and on after excavation, the characteristics of the cavity surrounding rock stress analysis , summed up the law , put forward a reasonable evaluation of segmented regions ; then select a reasonable combination of the characteristics of the project and its engineering geological characteristics evaluation parameters : Finally, traditional rock quality evaluation method Extension Evaluation Method GB BQ law and geomechanics RMR method cave surrounding rock rock mass quality evaluation and statutory rights by using analytic hierarchy cave surrounding rock rock mass quality evaluation of the results were analyzed to verify its practicality and consistency .
