土压平衡盾构法在城市隧道施工中已成功应用，提高了施工速度，节省了工时，提高了安全性。基于椭圆偏心率，建立了非等距系统的椭圆矩阵方程。通过对矩阵的分析，详细研究了力椭圆偏心的特性。将力椭圆应用于工程应用中的盾构机推进系统，研究了其与等距系统的区别。它为推力系统液压缸提供了一种新的布置，在大的变向力或不均匀的地质体下，这可以防止节段由于过度偏移载荷而破裂。(C)2010 Elsevier B.V.保留所有权利。
Earth Pressure Balance shield tunneling has been successfully adopted for urban tunneling and has resulted in increases in working speed, savings of man-hours and improved safety. Based on the ellipse eccentricity, the ellipse matrix equation for non-equidistant systems has been constructed. Through the analysis of the matrix, the characteristics of force ellipse eccentricity were investigated in detail. The distinction from the equidistant system was studied by applying the force ellipse to the thrust systems of shield machines in engineering applications. It provides a new arrangement for the thrust system hydraulic cylinders, under large change-of-direction forces or uneven geological bodies, which may prevent the segments from cracking due to an over-offset load.
