Research on Determination Loose Zone of Surrounding Rock in Highway Tunnel
With the vigorous development of China's highway construction, more and more stability problems of loose circle occurred in tunnel project, the deformation characteristics and distribution range of rock loose circle is very complex, which is of urgent need to further study. Based on geological data and construction program of Xi Shi slope tunnel, using the combined method of elastoplastic theoretical calculations and FLAC3D numerical simulation to analyze the distribution range of highway tunnel surrounding rock loose circle, and comparing it with the results of the measurements of surrounding rock deep displacement, thus, it is on the conclusion that grade IV rock loose circle of Xi Shi slope tunnel is in the range between 2.0 to 3.0m. Verifing the reliability of the method, and providing a strong guarantee for the design of support parameters.
