主要根据公路桥涵设计通用规范(JTG D60-2004)编制。在结果>荷载组合对话框中选择“自动生成”功能。a. 在荷载>移动荷载分析数据中定义移动荷载时，下面组合中的符号L 用ML 代替。b. 反应谱荷载工况的简称为ESP c. 在荷载>移动荷载分析数据中，将人群荷载按移动荷载定义，并在移动荷载工况中将其与其它汽车荷载子荷载工况进行组合时(在移动荷载工况中选择“组合”)，在定义人群荷载子荷载工况时，系数应取0.8(根据通用规范4.1.62-3-1=24 个): 1.2*D+1.2*PS+1.2*EV+1.4*EH+1.0*(SH+CR)+1.0*B+0. 5*STL+1.4*(L+IL+CF) +1.4*0.7*LS+1.4*0.7*CRL
