中文摘要：
以长春地铁大量施工监测数据为基础,运用Peck理论公式,在公式中添加了地表最大沉降修正系数α和沉降槽宽度修正系数β,确定了适用于长春地区的修正系数取值范围,并利用修正后的Peck公式对横向地表沉降进行预测。对比实测数据分析表明：当α取0.6~0.9、β取0.5~0.9时,Peck预测修正曲线和实测数据误差较小,适用于长春地铁工程实践,能较好地预防地铁施工事故的发生。
英文摘要：
Based on a large number of construction measured data of Changchun Subway,we introduce the maximum surface subsidence correction coefficient α and the width of the settlement trough correction factor β to correct Gaussian equation which was used to calculate the lateral surface subsidence,and determine the range of the correction coefficient.The analyzing results of comparing the real measured data show that：When α is 0.6~0.9,β is 0.5~0.9,the error between Peck forecast correction curve and the real measured data is small.The correction formula can be better applied to the subway engineering in Changchun and prevent the happening of the subway accident.
