Discussion on the calculation method of the deep buried tunnel surrounding rock loose pressure Yongfeng Yun1,2,a, Delun Wu1,b 1 School of Civil Engineering ,Chongqing University Chongqing 400045, China; 2 School of Architectural and Civil Engineering, Xi’an University of Science and Technology, Xi’an 710054, China a ygute@163.com Key words: Loose surrounding rock pressure, modified, continuity, calculation method Abstract.
Our country "highway tunnel design specifications" recommended the calculation of the surrounding rock vertical equipartition loose pressure calculation, according to through statistic analysis many tunnel materials, studied out the experience formula is (6) Where, ha is the average height of natural collapsing arch, ; S is surrounding rock level; γ is surrounding rock volume weight(kN/m3); ω is width influence coefficient, . i is surrounding rock pressure increase or decrease rate of B increase or decrease 1 m , with B = 5 m as a benchmark, when B<5, take ; when B>5 ,take ; In the above produce the vertical pressure produced at the same time, the tunnel also have appeared lateral pressure, namely the surrounding rock horizontal equipartition loose pressure e,
