摘要:
以杭州地铁机场快线某区间盾构工程为背景,选取了刀盘转速、刀盘扭矩、盾构机总推力、推进速度、平均土仓压力这5个盾构掘进参数。针对黏土地层,采用数理统计方法,分析了这5个盾构掘进参数之间的相关性,并分析了埋深对其影响。结果表明:盾构机总推力与刀盘扭矩、平均土仓压力与刀盘转速、平均土仓压力与总推力、盾构机总推力与刀盘转速之间具有一定的相关性;盾构机总推力、平均土仓压力与隧道埋深成正相关。结合盾构掘进过程中轴线地表沉降数据,从统计学角度确定盾构掘进参数的合理控制范围。
Abstract:
Based on the subway shield project in a section of Hangzhou Airport Express,five shield parameters are selected: cutter head speed, cutter head torque, total thrust of shield machine, advancing speed and average chamber earth pressure. For clay stratum, the correlation between the five shield parameters is analyzed by mathematical statistics, and the influence of buried depth on it is analyzed. Combined with the axis surface settlement data during shield tunneling, the reasonable control range of shield parameters is determined from the perspective of statistics. The results show that there is a certain correlation between the total thrust of shield machine and cutter head torque,the average chamber earth pressure and cutter head speed,the average chamber earth pressure and total thrust,and the total thrust of shield machine and cutter head speed;the total thrust and average chamber earth pressure of shield machine are positively correlated with the buried depth of tunnel Combined with the axial surface settlement data in the shield tunneling process, the reasonable control range of shield tunneling parameters is determined from statistics.
