• In most cases , it was found that the jb criterion is safer than hg specification , but adverse result was obtained when r / r is close to 0 . 8 and d / t is too small ( less than 40 ) . code in c language was worked out for simplifying the calculation
  在大多数情况下，按照jb标准对此种结构进行补强设计时其安全裕度要比hg标准为高；但是当开孔率接近0 . 8且d t很小时(不大于40 ) ，依jb标准补强设计后的安全裕度反而较按hg规范计算结果要小。
