1.爆破压力强度:未加补强元件(S_R=1.0和 S_R<1.0)的13个试件,除#635和#271外,其余试件的计算强度与试验结果都很接近,误差约在±10%以内(见表5)。#271试件因制造时有缺陷,试验前对腹部焊缝进行了修补,焊缝尺寸 B 由20mm增加到50mm,加宽段的长度为100mm,这对腹部起了一定的 1. Burst pressure strength: 13 specimens without reinforcement (S_R = 1.0 and S_R <1.0) except for # 635 and # 271, the strength of the rest of the specimens are very close to the experimental results, the error is about ± 10% or less (see Table 5). # 271 The specimen was defective due to manufacturing. The abdominal weld was repaired before the test. The size B of the weld was increased from 20 mm to 50 mm. The length of the widened section was 100 mm, which made the abdomen somewhat
