Abstract

Based on the similarity theory, the subway tunnel - across ground fissures formation dynamic interaction model test was designed. Through the analysis of the model test results, soil pressure and the contact pressure of different forms of piecewise horseshoe subway tunnel under the train load were system studied. Based on the related experimental data analysis, the following conclusion can be learned: when section tunnel did not fall, the ground soil pressure of surrounding rock and integral phase is similar, but after activities led to the decrease of the plate on the ground fissures, the soil pressure value and the overall comparatively large difference; Section tunnel compared to the original static earth pressure is increased; Sectional tunnel with integral tunnel close to the contact pressure distribution regularity, but caused by ground fissure activity on plate, after falling in the upper plate Y1 series on earth pressure caused by the formation escapes the numerical are larger than in the footwall Y2.
