2、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,8,0,280k,9,2359,280k,10,2886,2400k,11,1836,2750k,12,0,2750l,1,2l,2,
