针对非线性系统锂电池剩余电量(State of Charge,SOC)估计常用算法——安时积分法初值精度要求高、累计误差大的问题,提出了基于扩展卡尔曼滤波(Extended Kalman Filter,EKF)算法的SOC估计方法。通过建立合理的电池模型,利用MATLAB仿真在恒流工况下证明:安时积分法的平均误差为2.7%,EKF算法在无初始误差和存在初始误差两种工况下降低平均误差分别为0.97%和1.3%。最后通过ADVISOR 2002软件仿真验证了锂电池工作在两种动态电流工况下,基于EKF的SOC估计平均误差分别为1.06%、1.13%,符合SOC估计精度要求。

盾构隧道施工过程中若注浆参数选择不合理,将导致地表及周围建筑物发生坍塌和沉降,严重影响城市交通。以太原地铁2号线某区间盾构隧道施工为依托,结合工程施工资料和数值模拟软件,研究注浆比例系数、注浆压力和浆液弹性模量对地表沉降的影响规律,并对注浆参数进行优化、评价及应用。研究结果表明:地表沉降随着注浆比例系数和注浆压力的增加而减小,随浆液弹性模量的增加无明显变化;优化后的合理注浆比例系数为1.7、注浆压力为0.3 MPa;首次引入斜率评价法客观评价注浆参数对地表沉降的影响因次,得出注浆压力、注浆比例系数和浆液弹性模量的影响系数分别为1.53、1.05、0.48。优化参数工程应用后,盾尾空隙实测填充率达到91.3%,浆液固结体强度高于6 MPa,地表沉降量控制在20 mm以内,符合工程标准。
