Abstract

Abstract:

With the increasing number of underground roadways built in high-intensity earthquake zones in western China，and ground motion loads will cause various earthquake damages in the roadways，this has aroused the attention of the academic community to the seismic resistance of the roadways，but there are few pressure arches in the academic community.The dynamic load response law of high altitude and its influencing factors were analyzed.Therefore，this paper studied the change law of pressure arch height under seismic dynamic load for deep horseshoe-shaped roadways.Taking the flood drainage roadway of Xiaomaliu tailing reservoir in Xichang，Sichuan Province as an example，based on $F L A C 3 D$ numerical simulation orthogonal test，classic elastoplastic theory and pressure arch theory，this paper studied the influence law of the surrounding rock level，the buried depth of the roadway，the strength of the ground motion load，and the action time of the ground motion load，on the pressure arch height of surrounding rock in the vertical direction of the vault.Based on the conclusions of numerical simulation，a multiple regression prediction model of surrounding rock pressure arch and a time series prediction model of pressure arch height were established.The correlation degree of each influencing factor was studied through the correlation analysis of various factors，and the correctness of the conclusion was verified through comparative analysis.Based on this，corresponding relations between pressure arch height and surrounding rock level，roadway buried depth，ground motion load intensity，and ground motion load action time have been established，and the time effect of earthquake was considered in this paper，and the time correction of the regression model was proposed，which is more suitable for pressure arch height prediction under actual conditions.Some research results were obtained：Pressure arch height H and surface dynamic load amplitude A，dynamic load action time t，roadway buried depth h and surrounding rock grade SRC is positively correlated.And according to the analysis of MATLAB correlation degree，the order of the degree of influence of each factor is：Surrounding rock grade>dynamic load strength>dynamic load action time>roadway buried depth.Advance grouting support should be considered during construction to maintain the stability of the pressure arch.The seismic resistance of the weak surrounding rock should be considered to increase the support strength，and the pre-reinforcement treatment should be performed on the top of the roadway.The research results of the thesis have certain reference significance for the construction and support design of deep buried roadways.

Key words: deep buried tunnel, seismic dynamic load, pressure arch height, numerical simulation, time series, grey correlation analysis
