2、的段数，这样才能做出规整的箱梁截面网格划分，也就保证了变截面箱梁桥各截面的网格模式相同，建议对于变化急剧的两边截面应使得线足够的短。并不是划分越密越可能成功，而是线越短越可能成功3。通过梁节段两端对应的截面建立taper截面，定义好桥的线形后，指定每段线对应的taper截面。4、可以用slist命令查看生成截面的性质，加深对secread 命令的理解以下例进行说明：-截面图-截面图 全梁1/2图示-截面命令流finish/clear/prep7k,1k,2,2750k,3,3350,2400k,4,5450,2750k,5,6700,2850k,6,6700,3050k,7,0,3050k,8
