摘要
基于随机介质理论推导出单孔圆形断面隧道以及双孔圆形断面隧道开挖条件下地表沉降公式,同时通过MATLAB编程实现对昆明轨道交通4号线实测断面的双孔隧道地表沉降预测分析。此外,根据4号线昆明东站—麻苴站区间隧道沿线建筑的统计分析,对盾构隧道沿线区域进行基于双孔隧道的影响分区划分,结果表明双孔隧道开挖相对于单孔隧道的影响区有一定的扩大。
Based on the stochastic medium theory,the formula of surface settlement caused by excavation of singletube circular section tunnel and double-tube circular section tunnel is deduced.At the same time,the prediction of surface settlement of the measured sections of double-tube tunnel of Kunming Rail Transit Line 4 is realized by MATLAB programming.In addition,according to the statistical analysis of the buildings along the tunnel alignment of Kunming East Railway Station to Maju Station on Line 4,the impact zones are divided according to the influence of the double-tube tunnel.The results show that the impact zone of the double-tube tunnel has a certain expansion compared to that of the single-tube tunnel.
